The Industrial Internet of Things (IIoT) has revolutionized industrial production. However, severe electromagnetic interference (EMI) from factory equipment presents significant challenges to industrial wireless communication, making it difficult to meet the determinism requirements. Current research primarily relies on statistical analysis, treating EMI as background noise and random pulses. This approach fails to capture and predict real-time EMI information, thus making it difficult to ensure deterministic Quality of Service (QoS) in wireless networks. Our research reveals that welding-induced EMI exhibits deterministic patterns and has a strong corrleation with industrial control instructions. Based on these findings, a modeling method is proposed that treats welding-generated EMI as a time series. Parameters were successfully extracted from measurement data, and the method's performance was effectively validated. This method demonstrates broad applicability and can be extended to measure and model EMI from various industrial production equipment. In the future, it could utilize industrial control instructions to predict real-time EMI information, facilitating efficient wireless network resource management and meeting the deterministic transmission requirements of wireless communications.

Autonomous Positioning Algorithm for UE in Cellular Networks 15th

Autonomous Positioning Algorithm for UE in Cellular Networks

The positioning techniques in wireless cellular networks detect and receive signals transmitted by the user equipment (UE) through base stations (BS), then the network side uses the time difference of arrival (TDOA) values carried in the received signals to calculate UE’s position. However, if the network side doesn’t report the positioning information to the UE, UE will never know its positioning result. Besides, a BS can accurately locate the UE within its coverage area, the security issue of UE needs to be considered. In order to improve the autonomy and security of UE, in this paper, we propose an autonomous positioning algorithm for the UE in cellular networks. The UE uses TDOA measurements and multiple UE positioning results sent by the network side to inversely calculate the positions of the BS participating in the positioning. After that, the UE can use calculated BS position coordinates and TDOA values measured by UE itself to calculate its position independently. The simulation results show that the method is effective, and the error of the calculated BSs’ coordinates is within the acceptable range. © 2021, ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering.

IEEE International Conference on communications in China (ICCC)

作者： Xiang Gao Tao Peng Ministry of Education Wireless Signal Processing and Network Lab Key Laboratory of Universal Wireless Communications Beijing University of Posts & Telecommunications Beijing China

Data transmission over mobile voice channel (DoV) suffers from vocoder compression and smartphone de-noising. Most previous algorithms ignore these two factors leading to the generated signal being distorted severely during real network transmission. This paper proposes a data modulation algorithm that maps data on the amplitude of different frequency components, and combined with interpolation 0 in frequency domain to obtain short-time stability. Then, a recurrent neural network (RNN) based compensation algorithm is proposed to compensate for distorted signal. As a result, this paper achieves 3.1kb/s data rate with an average 4.5% bit error rate (BER) in real network experiments. Numerical results suggest that the proposed algorithm has a considerable advantage in resisting smartphone de-noising and is capable of reducing distortion generated during transmission.

Coverage is crucial to the commercial success of New Radio, directly affecting the quality of service and network construction cost. Physical Uplink Control Channel (PUCCH) is a bottleneck channel, and its coverage enhancement technology needs to be studied as a priority. For scenarios requiring coverage enhancement, the signal-to-noise ratios of the receivers are relatively low, and channel estimation is the bottleneck in terms of link-level performance. Therefore, it is necessary to consider sequence-based PUCCH transmission schemes, which can provide less needed demodulation signal-to-noise ratio. In this paper, a serial cascade splicing sequence scheme is proposed and discussed. In this scheme, the receiver first performs sequence detection on the first half of the sequence to initially estimate the range of sequence numbers. Then the sequence detection is performed on the second half of the sequence. Finally, the detected sequence number is converted into bit information. This scheme can reduce the number of sequence detections and, thus, the complexity of the receiver. The simulation results show that the method can effectively improve transmission reliability.

IEEE Conference on Vehicular Technology (VTC)

作者： Yuge Cao Ziyuan Qiu Hang Long Wireless Signal Processing and Network Lab Key Laboratory of Universal Wireless Communications Ministry of Education Beijing University of Posts and Telecommunications Beijing China

Future networks will need to support more usage scenarios, including higher speed scenarios and ultra-reliability scenarios for which the current waveforms are not suitable. Recently, the proposed orthogonal time frequency space (OTFS) modulation proves to be robust to Doppler spead, but it uses a conventional linear receiver which is susceptible to multipath channel gains and has high complexity. In this paper, we propose a sequence spread modulation scheme to improve system reliability. The proposed scheme spreads symbols to the Doppler domain before OTFS modulation. At the receiver, we develop a Rake receiver over the Doppler domain. Simulation results show that the performance of the proposed sequence modulation scheme is almost independent of the channel multipath gains compared to a conventional linear receiver based on OTFS, which means the performance of the proposed receiver is always close to the best performance of a linear receiver.

IEEE Conference on wireless communications and networking

The fifth-generation (5G) wireless network is expected to support emerging applications requiring ultra high reliability and low latency, such as self-driving cars, factory automation (industry 4.0), and smart grid, known as ultra-reliable and low-latency communications (URLLC). Uplink grant-free (GF) transmission is considered as a promising technology for supporting the rigorous requirements of URLLC by saving the time of requesting/waiting for the scheduling grant and supporting the K-repetition transmission. Besides, the intercell interference (ICI) in uplink multi-cell GF transmission is another critical issue to be solved. In this paper, we propose an interference-aware based radio resource configuration framework of URLLC uplink GF transmission which means that we can configure the radio resources by utilizing the available interference information to mitigate the impact of severe ICI on the transmission performance in URLLC. Numerical results show that, the proposed scheme can greatly improve the total transmission reliability and has higher scalability and robustness compared to prior art solutions under the condition of satisfying the transmission delay requirement and resource constraint.

The Cell-Free Massive Multiple-Input Multiple-Output (CF-MIMO) system is a promising technology for beyond-fifth-generation (B-5G) networks. It involves deploying multiple access points (APs) with multiple antennas to serve groups of users (UEs) cooperatively. In this paper, we introduce two algorithms that utilize big data technology for interference identification and signal-to-interference-plus-noise ratio (SINR) prediction. These algorithms effectively identify user-level interference information and provide support for resource allocation. They outperform traditional machine learning methods in terms of accuracy, time efficiency, and computation complexity by a significant margin. To establish the theoretical foundation, we derive the closed form of the average SINR based on large-scale fading coefficients (LSFCs). Our results demonstrate that our algorithms significantly enhance prediction accuracy by 50%-75% and achieve an impressive 8-to 80-fold improvement in training efficiency compared to the benchmark scheme.

作者： Chang Yuan Tao Peng Kexin Zhang Hongyuan Shu Wenbo Wang Wireless Signal Processing and Networks Laboratory (WSPN) Key Laboratory of Universal Wireless Communication Ministry of Education Beijing University of Posts and Telecommunications (BUPT) Beijing P.R. China

Satellite constellation is envisioned as an important approach to enhancing the capability of existing networks. Technologies such as Network Function Virtualization (NFV) and Service Function Chain (SFC) have been proposed to make satellites much more tolerant to different kinds of service requests. Owing to Software-Defined Networks (SDN), satellite constellations can be managed in a more flexible manner. However, due to the high variability of constellation and multi-types of Virtual Network Functions (VNFs), it becomes a major challenge to select appropriate instances of VNFs to concatenate for routing when orchestrating resources to map SFC requests. In this paper, we investigate SFC Mapping Problem (SFC-MP) in a dynamically changing logical segmented network to provide stable communication service. We formulate the problem as a Binary Integer Programming (BIP) model. In addition, we propose a new Continuous Logical Segmented Network Resource Aware Routing (LSNRAR-Continuous) algorithm for SFC requests routing to achieve network load balancing and reduce the impact of VNF migration on services. Simulation results show that the algorithm can effectively solve the SFC-MP problem, and the proposed algorithm has higher performance in terms of average delay, mapping cost and service stability compared with existing literature algorithms.

Toaddress the demands of high data rate transmission, multifunctionality, and miniaturization in modern communication devices, a novel design for a frequency-reconfigurable terahertz patch antenna is proposed using graphene. The antenna employs a coplanar waveguide feeding structure, which facilitates impedance matching. Three graphene patches are strategically placed and serve as tuning switches within the antenna gap. By controlling the conductivity of graphene, the effective length of the antenna is influenced, enabling frequency switching. The antenna achieves frequency reconfigurable within the 2.705- 3.569 THz frequency range, exhibits good impedance matching, with reflection coefficients all below -17 dB, and maintains a stable maximum radiation gain within 2.9-3.1 dBi. © 2024 IEEE.

IEEE Conference on Vehicular Technology (VTC)

Direction-of-arrival (DoA) estimation is an essential technique in wireless communication, which is widely used for many applications. With the ever-increasing demand of the applications for real-time DoA estimation, phase interferometer-based methods are popular because of their extremely low computational complexity. In this paper, a phase interferometer with an iterative mechanism is proposed for two-dimensional (2D) DoA estimation with a uniform circular array. The phase differences of the selected antenna baselines are the inputs of the proposed method, which are calculated from the received signal. In the proposed method, the 2D DoA is solved by the iterative weighted least squares method based on the relations between the DoA and the phase differences, where the weights are assigned to different baselines and are designed with reference to the noise resistance capability of the corresponding phase differences. Additionally, the weights are updated with iterations. The simulation results indicate that when compared with the benchmarks, the DoA estimation with the proposed method enjoys superior estimation performance without compromising computational complexity.
