Enhanced data detection employing compressed sensing In wireless communications

Abstract

A framework and algorithm employing compressed sensing (CS) for orthogonal frequency division multiplexing (OFDM) systems is proposed. A compressive iterative interference cancellation for OFDM signal is presented. Prior knowledge of communication system is exploited to enhance data detection performance. Simulation results indicate that such an advanced data detection and receiver yields significant gains in bit error rate (BER) at low sampling rates.
