This work investigates suitable MAC protocols for medical optical wireless body‐area networks (WBANs), focussing on multiple access management. Using realistic channel models, we evaluate the network performance in terms of energy efficiency, quality‐of‐service and scalability for different IEEE protocols, for both intra‐ and extra‐WBAN connectivity in

This paper proposes a reconfigurable intelligent surface‐based deep reinforcement learning MAC (RIS‐DRL‐MAC) protocol for terahertz mesh networks. By embedding RIS perception into the MAC decision loop and using a distributed TD3 algorithm, the proposed scheme achieves a cross‐layer optimisation of beam direction, access timing and RIS phase control ...

Design and Optimization of Finite Alphabet Waveforms for Multiple‐Antenna Radar Covariance Matching
This article propose a novel method for finite‐alphabet waveform generation based on constrained matrix decomposition. It also expands theoretical feasibility bounds for generating covariance matrices with binary waveforms, proves that matrices from autoregressive processes are always realizable and introduces an optimal adjustment procedure for ...
