STAR-RIS Assisted Covert Communications in NOMA Systems
Han Xiao, Xiaoyan Hu, Tong-Xing Zheng +1
Covert communications assisted by simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) in non-orthogonal multiple access (NOMA) systems have bee…
Weighted Sum Rate Enhancement by Using Dual-Side IOS-Assisted Full-Duplex for Multi-User MIMO Systems
Sisai Fang, Gaojie Chen, Chong Huang +4
This paper established a novel multi-input multi-output (MIMO) communication network, in the presence of full-duplex (FD) transmitters and receivers with the assistance of dual-sid…
Copula-based Performance Analysis for Fluid Antenna Systems under Arbitrary Fading Channels
Farshad Rostami Ghadi, Kai-Kit Wong, F. Javier Lopez-Martinez +1
In this letter, we study the performance of a single-user fluid antenna system (FAS) under arbitrary fading distributions, in which the fading channel coefficients over the ports a…
Distributed Information Bottleneck for a Primitive Gaussian Diamond MIMO Channel
Yi Song, Hao Xu, Kai-Kit Wong +2
This paper considers the distributed information bottleneck (D-IB) problem for a primitive Gaussian diamond channel with two relays and MIMO Rayleigh fading. The channel state is a…
