Secrecy Analysis for MISO Broadcast Systems with Regularized Zero-Forcing Precoding
CoRR, 2023 There are some errors in Eq. (28) of Section IV regarding the convergence rate. The asymptotic regime does not hight the same increasing rate of dimensions, which is not totolly correct. The proof in Appendix C is not sufficient enough.

IET Communications, Volume 20, Issue 1, January/December 2026.This paper addresses channel estimation in mmWave (millimetre wave) hybrid MIMO (multiple‐input multiple‐output) systems impaired by residual transceiver hardware nonidealities, modelled as additive non‐Gaussian noise via Bussgang decomposition. A hyperparameter‐free maximum Versoria criterion (MVC)‐based channel estimator is proposed, featuring a ...

Deep Learning-Aided Delay-Tolerant Zero-Forcing Precoding in Cell-Free Massive MIMO
, 2022 In the context of cell-free massive multi-input multi-output (CFmMIMO), zero-forcing precoding (ZFP) is superior in terms of spectral efficiency. However, it suffers from channel aging owing to fronthaul and processing delays.

IET Communications, Volume 20, Issue 1, January/December 2026.ABSTRACT Millimeter‐wave (mmWave) Internet‐of‐Vehicles (IoV) communications rely on large antenna arrays to combat severe path loss and to provide high beamforming gains. However, practical vehicular deployments often adopt analog or hybrid beamforming with constant‐modulus constraints, leading to a highly non‐convex joint beamforming design problem ...

Partial zero-forcing precoding for the interference channel with partially cooperating transmitters [PDF]
2010 IEEE International Symposium on Information Theory, 2010 A communication model is considered in which the classic two-user Gaussian interference channel is augmented by noiseless rate-limited digital conferencing links between the transmitters. We propose a partial zero-forcing precoding strategy based on a shared-private rate splitting scheme at the transmitter, in which each transmitter communicates part ...

Propagation time for probabilistic zero forcing [PDF]
, 2018 Zero forcing is a coloring game played on a graph that was introduced more than ten years ago in several different applications. The goal is to color all the vertices blue by repeated use of a (deterministic) color change rule. Probabilistic zero forcing

IET Communications, Volume 20, Issue 1, January/December 2026.The multi‐agent Deep Reinforcement Learning (DRL)‐based uplink power control algorithm significantly improves energy efficiency using multi‐agent Deep Deterministic Twin Policy Gradient (MATD3) with dynamic clustering. The Proposed algorithm outperforms single‐agent DRL and classical methods.

Partial Zero-forcing Precoding for Interference Channels with Limited Transmitter Cooperation [PDF]
, 2011 This thesis looks at the problem of designing a coding strategy for interference channels with rate-limited transmitter cooperation. We first consider a simple communication model in which the classic two-user Gaussian interference channel is augmented ...

Multiuser precoding scheme and achievable rate analysis for massive MIMO system
EURASIP Journal on Wireless Communications and Networking, 2018 We analyze the downlink multiuser precoding of massive multiple input multiple output (MIMO) system, where the base station (BS) has ideal channel state information (CSI) and adopts three types of different linear precoding schemes, i.e., maximum ratio ...
