Pilot Spoofing Attack on the Downlink of Cell-Free Massive MIMO: From the Perspective of Adversaries
The channel hardening effect is less pronounced in the cell-free massive multiple-input multiple-output (mMIMO) system compared to its cellular counterpart, making it necessary to estimate the downlink effective channel gains to ensure decent performance. However, the downlink training inadvertently creates an opportunity for adversarial nodes to launch pilot spoofing attacks (PSAs). First, we demonstrate that adversarial distributed access points (APs) can severely degrade the achievable downl…

Precoder Design for Massive MIMO Downlink with Matrix Manifold Optimization
We investigate the weighted sum-rate (WSR) maximization linear precoder design for massive multiple-input multiple-output (MIMO) downlink. We consider a single-cell system with multiple users and propose a unified matrix manifold optimization framework applicable to total power constraint (TPC), per-user power constraint (PUPC) and per-antenna power constraint (PAPC). We prove that the precoders under TPC, PUPC and PAPC are on distinct Riemannian submanifolds, and transform the constrained prob…

On Stochastic Fundamental Limits in a Downlink Integrated Sensing and Communication Network
This paper aims to analyze the stochastic performance of a multiple input multiple output (MIMO) integrated sensing and communication (ISAC) system in a downlink scenario, where a base station (BS) transmits a dual-functional radar-communication (DFRC) signal matrix, serving the purpose of transmitting communication data to the user while simultaneously sensing the angular location of a target. The channel between the BS and the user is modeled as a random channel with Rayleigh fading distribut…

Joint Active And Passive IRS Aided Wireless Communication: Elements Allocation and Achievable Rate
Equipping reflecting elements at the active intelligent reflecting surface (AIRS) enhances signal amplification capability but meanwhile incurs non-negligible amplification noise, which thus challenges the determination of elements allocation for maximizing achievable rate in multi-cooperative AIRS and passive IRS (PIRS) jointly aided wireless communication system. To tackle this issue, we consider the downlink communication from a single-antenna transmitter (Tx) to a single-antenna receiver (R…
