Multiple Choice Hard Thresholding Pursuit (MCHTP) for Simultaneous Sparse Recovery and Sparsity Order Estimation
Samrat Mukhopadhyay, Himanshu Bhusan Mishra
We address the problem of sparse recovery using greedy compressed sensing recovery algorithms, without explicit knowledge of the sparsity. Estimating the sparsity order is a crucia…
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…
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…
Uplink Sum-Rate and Power Scaling Laws for Multi-User Massive MIMO-FBMC Systems
Prem Singh, Himanshu B. Mishra, Aditya K. Jagannatham +2
This paper analyses the performance of filter bank multicarrier (FBMC) signaling in conjunction with offset quadrature amplitude modulation (OQAM) in multi-user (MU) massive multip…
