Is Downlink Training Necessary for User-Centric Cell-Free RSMA Systems With Mobile Users?
Ravi Kiran Palla, Dheeraj Naidu Amudala, Rohit Budhiraja
We study the spectral efficiency (SE) of a ratesplitting multiple access (RSMA) enabled multi-clustered cell-free (CF) massive multiple-input multiple-output (mMIMO) system. The ac…
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…
Hardware-Aware Pilot Decontamination Precoding for Multi-cell mMIMO Systems With Rician Fading
Harshit Kesarwani, Dheeraj Naidu Amudala, Venkatesh Tentu +1
We consider a hardware-impaired multi-cell Rician faded massive multi-input multi-output (mMIMO) system with two-layer pilot decontamination precoding, also known as large-scale fa…
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…
