TL;DR: In this paper, the authors studied the minimum signal-to-interference-plus-noise ratio (SINR) achieved by the optimal linear precoder (OLP) that maximizes the minimum SINR subject to a given power constraint for any given RIS phase matrix.

TL;DR: Simulation comparisons between the Welch-bound equality spread multiple access (WSMA)-based NOMA and multi-user multiple-input-multiple-output (MU-MIMO) are presented, and a number of methods to reduce the implementation complexity and delay of both uplink (UL) and downlink (DL) N OMA-based transmission are proposed, as different ways to improve its efficiency.

TL;DR: Simulation results show that RISs can outperform half-duplex relays with a small number of passive reflecting elements while large RISs are needed to outperform full-duple relays.

TL;DR: In this article, the ergodic rate performance of a multi-user multiple-input-single-output (MISO) system with double-scattering channels is investigated.

TL;DR: This article aims to illustrate the structural properties of integer programs that can be formulated as clique problems through multiple examples in communications and signal processing, mainly in maximum access for nonorthogonal multiple access networks, throughput maximization using index and instantly decodable network coding, collision-free radio-frequency identification networks, and resource allocation in cloud-radio access networks.
