Asymptotic Mutual Information Analysis for Double-scattering MIMO Channels: A New Approach by Gaussian Tools
Xin Zhang, Shenghui Song
The asymptotic mutual information (MI) analysis for multiple-input multiple-output (MIMO) systems over double-scattering channels has achieved engaging results, but the convergence…
Outage and Finite-SNR DMT Analysis for IRS-aided MIMO Systems: How Large IRSs Need to Be?
Xin Zhang, Xianghao Yu, S. H. Song
Intelligent reflecting surfaces (IRSs) are promising enablers for high-capacity wireless communication systems by constructing favorable channels between the transmitter and receiv…
Bias for the Trace of the Resolvent and Its Application on Non-Gaussian and Non-centered MIMO Channels
Xin Zhang, S. H. Song
The mutual information (MI) of Gaussian multi-input multi-output (MIMO) channels has been evaluated by utilizing random matrix theory (RMT) and shown to asymptotically follow Gauss…
IRS-aided MIMO Systems over Double-scattering Channels: Impact of Channel Rank Deficiency
Xin Zhang, Xianghao Yu, S. H. Song +1
Intelligent reflecting surfaces (IRSs) are promising enablers for next-generation wireless communications due to their reconfigurability and high energy efficiency in improving poo…
Angular resolution limit for deterministic correlated sources
Xin Zhang, Mohammed Nabil El Korso, Marius Pesavento
This paper is devoted to the analysis of the angular resolution limit (ARL), an important performance measure in the directions-of-arrival estimation theory. The main fruit of our…
