Received signal strength (RSS)-based location estimation is one of the most acceptable methods for localization in wireless sensor networks. However, am imperfection in the value of RSS due to various fading affects error in the estimated location results. Here, we have proposed to use fuzzy logic to rectify the uncertainty in the value of received signal strength which in turn results in more localization accuracy. The proposed localization algorithm first finds the interval for the maximal possible value of RSS received by an unknown node from the anchor node and then uses a similarity index to find out the best RSS value for an unknown node. The simulation results show that the proposed method leads to better per node localization accuracy and overall network localization accuracy at different node and anchor node densities as compared to the weighted centroid method. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Radio Frequency(RF) fingerprinting is one physical-layer authentication method for wireless communication, which uses the unique hardware characteristic of the transmitter to identify its true *** improve the performance of RF Fingerprint(RFF)based on preamble with fixed duration, a nonlinear RF fingerprinting method based on payload symbols is proposed for the wireless OFDM communication with the bit mapping scheme of QPSK. The wireless communication system is modeled as a Hammerstein system containing the nonlinear transmitter and multipath fading channel. A parameter separation technique based on orthogonal polynomial is presented for the estimation of the parameters of the Hammerstein system. The Hammerstein system parameter separation technique is firstly used to estimate the linear parameter with the training signal, which is used to compensate the adverse effect of the linear channel for the demodulation of the successive payload symbols. The demodulated payload symbols are further used to estimate the nonlinear coefficients of the transmitter with the Hammerstein system parameter separation technique again, which is used as the novel RFF for the authentication of the QPSK-OFDM device. Numerical simulations have verified the proposed method, which can also be extended to the OFDM signals with other bit mapping schemes.

Dual-Band Dual-Polarized Omnidirectional MIMO Antenna with Ultra-Low Profile for Vehicular communications

引用

IEEE Transactions on Vehicular Technology 2025年第6期74卷 9240-9251页

作者： Ke, Yan-Hui Zhou, Jian Chen, Jian-Xin Nantong University School of Information Science and Technology Research Center for Intelligent Information Technology Nantong226019 China Nantong Research Institute for Advanced Communication Technologies Chongchuan District Nantong226019 China

In this article, a dual-band dual-polarized (DP) omnidirectional multiple-input multiple-output (MIMO) antenna with ultra-low profile is proposed for vehicular communications. The vertically polarized element (VPE) is composed of a top-loaded metal disk, four bent arms and a round ground, which has a low profile of 0.049λL (λL represents the free space wavelength at the lowest operating frequency) and a broad band of 1.66 GHz to 4 GHz. It is evolved from a mono-conical antenna and eventually achieved an ultra-low profile while remaining the broad band by replacing the complete cone with four metal arms, adding a top-loaded metal disk and grounding structures, and the multiple bents of the four arms. After that, two horizontally polarized elements (HPEs) are meticulously designed and embedded in the ground and the top disk of the VPE, respectively. Benefiting from the low profile VPE, the planar HPEs and the compact embedding scheme, the proposed antenna has a profile of only 0.053λL. To verify the design, a prototype is manufactured and measured. The results indicate that the prototype has overlapping bands of 1.63-2.7 GHz and 3.22-3.82 GHz, gain variation in omnidirectional plane of below 2.4 dB, and isolation between ports of better than 25 dB. © 1967-2012 IEEE.

An Ultralow-Profile Dual-Wideband Antenna Based on Multiple Modes and Multiple Coupling for 5G Terminal Application

引用

IEEE Antennas and Wireless Propagation Letters 2025年第6期24卷 1432-1436页

作者： Yang, Xu Geng, Xin Shen, Miao-Peng Yang, Wen-Wen Kong, Wei-Bin Qin, Wei Chen, Jian-Xin Nantong University School of Information Science and Technology Nantong226009 China Nantong Research Institute for Advanced Communication Technologies Nantong226019 China Yancheng Institute of Technology Yancheng224000 China

An ultralow-profile dual-band antenna based on half mode substrate integrated waveguide (HMSIW) and shorted patches for 5G mobile terminal applications is proposed in this letter. The antenna has a height of only 0.5 mm (0.006λL) and occupies a footprint of 38.5 mm × 40 mm (0.43λL × 0.45λL). First, three modes are obtained by exciting the HMSIW antenna loaded with cross slots, specifically the TE110 mode at 3.5 GHz and the even/odd TE210 modes around 4.9 GHz, enabling dual-band operation. Next, by parasitizing two shorted patches on the left side and one on the bottom of the HMSIW, two modes at 3.5 GHz and one mode at 4.9 GHz are introduced. Based on this structure, three operating modes can be obtained respectively at 3.5 GHz and 4.9 GHz band, effectively overcoming the bandwidth limitations caused by the extremely low profile. Measured results show that the bandwidth of the antenna can cover partial N78 band from 3.4 GHz to 3.6 GHz and partial N79 band from 4.7 GHz to 5 GHz. The average efficiencies are −2.45 dB in the N78 band and −2.94 dB in the N79 band. This design provides a promising solution for ultralow-profile dual-wideband mobile terminal antennas. © 2002-2011 IEEE.

Mining of social media data has found widespread applications in recent times. Twitter feeds and Facebook posts are being used to device product marketing strategies, sentiment analysis, financial predictions and forebode alarming situations. Twitter feeds analysis can be applied for analysing the behaviour and experiences of medical practitioners. Doctors’ informal conversations on Twitter can provide deep insights about their work experiences, their concerns about the profession, their feelings – pathos or excitement they feel – and the affecting conditions. In the present work, Twitter feed of doctors along with the Twitter hashtags are used to collect data from tweets with hashtags such as #DoctorProblems. Afterward, data analysis was performed to determine the major problems faced by the members of the medical fraternity. These problems were categorised into five main categories. The multi-label naïve-Bayes classification algorithm and MapReduce paradigm was then implemented. The experimental results were evaluated and compared. It was found that the naïve Bayes multi-label classifier is superior to the MapReduce method for Twitter mining in terms of the time complexity. The obtained results could help employers provide better working environments to their doctors and make better informed decisions in order to help the concerned parties.

Water is essential for the life and nourishment of all living things. River water quality has deteriorated in recent years as a result of toxic wastes and contaminants. This rapid augmentation in water pollution is a major source of concern since it degrades water quality and renders it unsuitable for any usage. In India, Yamuna is considered one of the most important rivers in the northern region which plays a major role in development. In this work, we have focused on the Yamuna River water quality classification according to its usability as excellent, poor and unsuitable for drinking. To achieve this objective, we have presented a novel hybrid machine learning technique by taking the advantage of an ensemble learning mechanism. The proposed approach considers relief-based feature selection which helps to reduce the dimensionality, forward feature ranking which helps to consider the stage-wise features and a decision tree classifier. The performance of proposed water quality classification technique is compared with other classification techniques including Naïve Bayes, Support Vector Machine (SVM), bagged tree and boosted tree classifiers. The proposed approach achieves an overall accuracy of 99.65% which proves the robustness of this scheme in terms of predicting the water quality. © 2022 Bharati Vidyapeeth, New Delhi.

In this paper, comparative analysis of code performance of distinct optical 2-D codes belonging to the Prime code family have been examined. Various optical 2-D Prime codes such as Low-weight Prime sequence code (LW-PSC), Modified prime-hop code (MPHC), Extended prime-hop code (E-CHPC), Transposed-modified prime code (T-MPC), Transposed-sparse padded modified prime code (T-SPMPC) are considered. Hard-limiting Error Probability (HEP) equations of these codes are used to scrutinize the performance of these codes. Performance of one of the 2-D Prime codes, more specifically MPHC performs best in OCDMA systems where only Multi-user interference effect is considered. This optical 2-D MPHC code possesses very low BER value as compared to universally accepted standard with the increasing user count. MPHC provides robustness to multiple user interference affected OCDMA therefore very much apt for applications where simultaneous access of immense number of active user is required. © 2018, Bharati Vidyapeeth's institute of Computer Applications and Management.
