Joint Mutual Coherence and Total Coherence Pilot Design for OFDM Channel Estimation
IEEE Access, 2019 Existing works design the pilot based on the mutual coherence criterion or total coherence criterion alone. However, using the mutual coherence criterion or total coherence criterion alone to design the pilot will yield the sensing matrix which ...

Multiuser Massive MIMO Systems With Time-Offset Pilots and Successive Interference Cancellation
IEEE Access, 2019 This paper proposes time-offset pilots for a single-cell multiuser massive multiple-input multiple-output (MIMO) system and studies its performance under the minimum mean-squared error channel estimator and successive interference cancellation.
