Using a large number of power amplifiers brings serious nonlinear distortion to 5G communication systems, which becomes a challenging problem for conventional digital predistortion (DPD) to linearize signals. To address this challenge, we propose a digitally assisted nonlinearity suppression architecture for applications in multiple antenna arrays. In this architecture, we use an auxiliary array to generate a nonlinear cancelation signal to cancel with the main beam at the receiving end. We explore a two-step method to model the nonlinear signal and combine neural network to complete the modeling. In addition, we introduce a novel method for estimating and tracking the channel to update the model coefficients. To verify the proposed methods, we design a scene and compare the performance of our architecture with that of conventional DPD. Our experiments demonstrate that our proposed methods can significantly enhance the adjacent channel power leakage ratio performance by 12 dB while also optimizing in-band distortion. Moreover, our architecture outperforms conventional DPD approaches even with enhanced distortion. © 2023 John Wiley & Sons Ltd.

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.

Three dimension Multi processors System-on-Chip (3D-MPSoCs) hold promises to allow the development of compact and efficient devices. They support many applications on the same die, able of being mapped dynamically during the execution time. Each application may have different communication requirements. Quality-of-Service (QoS) can be implemented at the communication structure (CS) to support the communication requirements of the dynamic 3D-MPSoC. Our work proposes QoS 3D-HoC, a new 3D-CS that implements the QoS. We evaluate the performance of our architecture over several 3D-MPSoC synthetic and real traffic scenarios and estimate their impact overall CS performance. We compare our architecture against the previous 3D-CS with and without QoS and show that our approach meets the communication requirements while reducing the latency and power up to 87% and 39%, respectively when compared to single 3D-NoC.

In the high sea state environment, the echo of small and slow ship targets is often submerged by sea clutter, and the conventional adaptive detection often has serious missed detection phenomenon. The adaptive detector is mainly based on the different statistical distribution of the sea clutter texture. However, the spatial correlation of sea clutter has not been attracted enough attention. Considering that the texture components of sea clutter are highly correlated in adjacent range cells, this paper proposes an adaptive detector based on the spatial correlation characteristics of sea clutter. The detector performs joint generalized likelihood ratio detection on the echo vector in the cell under test (CUT) and the echo vectors in the reference cells around the CUT. By adjusting the control parameters a, the detector matches the statistical characteristics of sea clutter amplitude in the CUT. The effectiveness of the proposed detector is verified by using the real sea clutter data. The experiments show that the proposed detector has a significant improvement in detection performance, which compares with the original a matched filter (a-MF) and matched filter (MF). © 2022 IEEE.

MPSoCs are able to support multiple applications on the same chip. This flexibility also represents a vulnerability, turning the MPSoC security specially challenging. Most of the current MPSoCs security services are based on symmetric and public-key cryptographic mechanisms. So that, MPSoCs integrate a large set of keys that must be exchanged in an efficient and secure way. In such scenario, any security concept will be ineffective if the key management is weak. In this paper, we present the implementation of an on-chip hybrid communication (HoCs) security-based architecture, that combines bus and Network-on-chip (NoC), to address the efficient and secure key management at MPSoCs. The HoC implements dynamically the QoSS (Quality of Security Service) concept that allows the customization of security. We evaluate the effectiveness of our approach over several MPSoCs attack scenarios and estimate their impact on the overall performance. We show that our architecture can perform a fast detection of a wide range of attacks and a fast configuration of the different security policies for several MPSoC applications. Our hybrid approach saves upto 16% and 25% of communication latency and power consumption, respectively, when compared to the NoC-based architecture without any security.

Wide-Beam Designs for Terahertz Massive MIMO: SCA-ATP and S-SARV

Wide-Beam Designs for Terahertz Massive MIMO: SCA-ATP and S-...

Terahertz (THz) communication is expected to be one of the core enabling technologies for future systems. Due to the poor scattering and severe reflection loss of THz waves, the line-of-sight (LoS) communication is considered as a leading feature in THz multiple-input-multiple-output (MIMO) systems. To realize LoS communication, beam training is a promising scheme to find the beamforming vectors without leveraging explicit channel state information (CSI). In this context, a crucial issue for THz MIMO is how to design the beam codewords for realizing any expected radiation pattern during the training. In particular, the narrow beams can be realized by array response vectors whereas the wide-beam design is still an open problem. In this article, we propose two high-quality algorithms, namely, successive convex approximation (SCA)-based auxiliary target pursuit (SCA-ATP) and the sum of symmetrical array response vectors (S-SARVs), for offline design and real-time design, respectively. Numerical results show that SCA-ATP yields the best performance in terms of the beam-pattern error (BPE) compared with benchmarks, and S-SARV can achieve a close performance to SCA-ATP with low computational complexity. © 2014 IEEE.
