Deterministic pilot pattern allocation optimization for sparse channel estimation based on CS theory in OFDM system
Abstract Compressed sensing (CS)-based sparse channel estimation requires the sensing matrix with the minimum mutual coherence (MC), and its corresponding pilot pattern obtain optimal estimation performance. In order to minimize the MC of the sensing matrix, a deterministic optimized pilot pattern a...
