How much Training is Needed in Downlink Cell-Free mMIMO under LoS/NLoS channels?
Sai Manikanta Rishi Rani, Ribhu Chopra, Kumar Appaiah
The assumption that no LoS channels exist between wireless access points~(APs) and user equipments~(UEs) becomes questionable in the context of the recent developments in the direc…
PSA Based Power Control for Cell-Free Massive MIMO under LoS/NLoS Channels
Ashish Pratap Singh, Ribhu Chopra
A primary design goal of the cell-free~(CF) massive MIMO architecture is to provide uniformly good coverage to all the user equipments~(UEs) connected to the network. However, it h…
MIMO Radars and Massive MIMO Communication Systems can Coexist
Aparna Mishra, Ribhu Chopra
In this paper, we investigate the coexistence of a single cell massive MIMO communication system with a MIMO radar. We consider the case where the massive MIMO BS is aware of the r…
Impact of Mobility on Downlink Cell-Free Massive MIMO Systems
Abhinav Anand, Chandra R. Murthy, Ribhu Chopra
In this paper, we analyze the achievable downlink spectral efficiency of cell-free massive multiple input multiple output (CF-mMIMO) systems, accounting for the effects of channel…
Uplink Performance Analysis of Cell-Free mMIMO Systems under Channel Aging
Ribhu Chopra, Chandra R. Murthy, Anastasios K. Papazafeiropoulos
In this paper, we investigate the impact of channel aging on the uplink performance of a cell-free~(CF) massive multiple-input multiple-output (mMIMO) system with a minimum mean sq…
Outage Probability Analysis of IRS-Assisted Systems Under Spatially Correlated Channels
Trinh Van Chien, Anastasios K. Papazafeiropoulos, Lam Thanh Tu +3
This paper investigates the impact of spatial channel correlation on the outage probability of intelligent reflecting surface (IRS)-assisted single-input single-output (SISO) commu…
Performance Analysis of Cell Free Massive MIMO systems in LoS/ NLoS Channels
Sudarshan Mukherjee, Ribhu Chopra
In cellular communication systems, it is conventional to assume the absence of a line of sight (LoS) path between the users and their associated access points (APs). This assumptio…
