Pilot pattern optimization for compressed sensing based sparse channel estimation in OFDM systems

The frequency selective channel estimation problem in orthogonal frequency division multiplexing (OFDM) systems is investigated using compressed sensing (CS). Based on minimizing mutual coherence of the measurement matrix in CS theory, a criterion of optimizing the pilot pattern for the CS-based cha...
