Interference Suppression in Heterogeneous Massive MIMO Systems with Imperfect CSI [PDF]
Telecommunication Systems, 2021 Abstract Interference management is of paramount importance in heterogeneous massive mimo networks (HetNet). In this paper, an algorithm has been suggested to suppress the interference in large-MIMO HetNets with imperfect channel state information(CSI).

A Transceiver Design Based on an Autoencoder Network for Multi-Color VLC Systems
IEEE Photonics Journal, 2020 We propose a transceiver design method based on an autoencoder (AE) network for multi-color visible light communication (VLC) systems. Taking into account the chromaticity constraint described by MacAdam ellipses and the peak-value constraint of ...

Cutoff rate optimal binary inputs with imperfect CSI [PDF]
IEEE Transactions on Wireless Communications, 2006 We use the cutoff rate to study the optimal binary input distributions for the Rayleigh flat-fading channel with imperfect receiver channel state information (CSI). First, we evaluate the cutoff rate and analyze the optimal binary input as a function of the CSI quality and receiver SNR. Next, we study the limiting distributions - BPSK and on-off keying
