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…
Granger Causality Detection via Sequential Hypothesis Testing
Rahul Devendra, Ribhu Chopra, Kumar Appaiah
Most of the metrics used for detecting a causal relationship among multiple time series ignore the effects of practical measurement impairments, such as finite sample effects, unde…
