Hardware-Impaired Rician-Faded Cell-Free Massive MIMO Systems With Channel Aging

Venkatesh Tentu, Dheeraj N Amudala, Anish Chattopadhyay +1

We study the impact of channel aging on the uplink of a cell-free (CF) massive multiple-input multiple-output (mMIMO) system by considering i) spatially-correlated Rician-faded cha…

Low-Complexity ZF/MMSE Receivers for MIMO-OTFS Systems With Imperfect CSI

Prem Singh, Abhishek Gupta, Himanshu B. Mishra +1

Orthogonal time-frequency space (OTFS) scheme, which transforms a time and frequency selective channel into an almost non-selective channel in the delay-Doppler domain, establishes…

Hybrid Block Diagonalization for Massive MIMO Two-Way Half-Duplex AF Hybrid Relay

Arpita Singh Chauhan, Ekant Sharma, Rohit Budhiraja

We consider a multi-pair two-way amplify-and-forward massive multi-input multi-output (MIMO) hybrid relay with MIMO user-pairs. A hybrid relay has lesser number of radio frequency…

Linear Precoders for Non-Regenerative Asymmetric Two-way Relaying in Cellular Systems

Rohit Budhiraja, Karthik KS, Bhaskar Ramamurthi

Two-way relaying (TWR) reduces the spectral-efficiency loss caused in conventional half-duplex relaying. TWR is possible when two nodes exchange data simultaneously through a relay…
