Massive MIMO-OFDM Channel Acquisition with Time-Frequency Phase-Shifted Pilots
Jinke Tang, Xiqi Gao, Li You +5
In this paper, we propose a channel acquisition approach with time-frequency phase-shifted pilots (TFPSPs) for massive multi-input multi-output orthogonal frequency division multip…

Confined Orthogonal Matching Pursuit for Sparse Random Combinatorial Matrices
Xinwei Zhao, Jinming Wen, Hongqi Yang +1
Orthogonal matching pursuit~(OMP) is a commonly used greedy algorithm for recovering sparse signals from compressed measurements. In this paper, we introduce a variant of the OMP a…
