MM-Tap: Adaptive and Scalable Tap Localization on Ubiquitous Surfaces With mm-Level Accuracy IEEE Internet Things J. (IF 10.6) Pub Date : 2023-06-09 Yandao Huang, Cong Li, Fuwen Chen, Qian Zhang, Kaishun Wu
Transforming physical surfaces into virtual interfaces can extend the interaction capability of many exciting metaverse applications in the future. Recent advances in vibration-based tap sensing show promise for this vision using passive vibration signals. However, current approaches based on Time-Difference-of-Arrival (TDoA) triangulation suffer the impact of fluctuant wave velocity due to the dispersive

Optimum Performance Analysis and Receiver Design for OFDM-Based Frequency-Splitting SWIPT With Strong Nonlinear Effects IEEE Internet Things J. (IF 10.6) Pub Date : 2023-06-09 Akashkumar Rajaram, João Guerreiro, Rui Dinis, Dushantha Nalin K. Jayakody, Marko Beko
Multicarrier-based frequency splitting simultaneous wireless information and power transmission (FS-SWIPT) signals are very prone to nonlinear effects due to the combination of high-power energy harvesting (EH) subcarriers with low-power data subcarriers. In this article, we study the impact of nonlinear effects in FS-SWIPT signals, as well as ways to minimize these effects on the data transmission

Unsupervised Domain Adaptation for RF-Based Gesture Recognition IEEE Internet Things J. (IF 10.6) Pub Date : 2023-06-09 Bin-Bin Zhang, Dongheng Zhang, Yadong Li, Yang Hu, Yan Chen
Human gesture recognition with radio frequency (RF) signals has attained acclaim due to the omnipresence, privacy protection, and broad coverage nature of RF signals. These gesture recognition systems rely on neural networks trained with a large number of labeled data. However, the recognition model trained with data under certain conditions would suffer from significant performance degradation when

Distributed Neural Learning Algorithms for Multiagent Reinforcement Learning IEEE Internet Things J. (IF 10.6) Pub Date : 2023-06-09 Pengcheng Dai, Hongzhe Liu, Wenwu Yu, He Wang
In this article, the fully distributed neural learning algorithms by neural network approximation for networked multiagent reinforcement learning (NMARL) are studied. To tackle the convergence analysis of methods in NMARL with tremendous state-action space, most of the existing distributed algorithms are designed by linear function approximation, which however would fall into a situation of poor expression
