Multi-cell mMIMO IRS Systems With Impairments and Aging: Phase Optimization and Receiver Design
Rakesh Munagala, Dheeraj Naidu Amudala, Rohit Budhiraja
We consider the uplink of a hardware-impaired intelligent reflective surfaces (IRS) aided multi-cell massive multiple-input multiple-output (mMIMO) system with mobile user equipmen…
Variational Learning Algorithms For Channel Estimation in RIS-assisted mmWave Systems
Milind Nakul, Anupama Rajoriya, Rohit Budhiraja
We consider the problem of estimating the channel in reconfigurable intelligent surface (RIS) assisted millimeter wave (mmWave) systems. We propose two variational expectation maxi…
OTFS Channel Estimation And Data Detection Designs With Superimposed Pilots
Himanshu B. Mishra, Prem Singh, Abhishek K. Prasad +1
This work proposes a superimposed pilot (SP)-based channel estimation and data detection framework for orthogonal time-frequency space (OTFS) scheme, wherein low-powered pilots are…
FD Cell-Free mMIMO: Analysis and Optimization
Soumyadeep Datta, Ekant Sharma, Dheeraj Naidu Amudala +2
Cell-free (CF) massive multiple-input-multiple-output (mMIMO) deployments are usually investigated with half-duplex nodes and high-capacity fronthaul links. To leverage the possibl…
Full-Duplex Cell-Free mMIMO Systems: Analysis and Decentralized Optimization
Soumyadeep Datta, Dheeraj Naidu Amudala, Ekant Sharma +2
Cell-free (CF) massive multiple-input-multiple-output (mMIMO) deployments are usually investigated with half-duplex nodes and high-capacity fronthaul links. To leverage the possibl…
