Information Technology Journal, 2013, 12(5), 1040-1044.

Abstract

An algorithm of channel estimation was proposed based on the theory of Compressive Sensing (CS) by analyzing the sparse characteristic of underwater acoustic channel for Orthogonal Frequency Division Multiplex (OFDM), Comparing with conventional Least Square (LS) estimation algorithm, the algorithm had good performance with less pilots, which improved the spectral efficiency of communication system. The result of simulation has analyzed the performance of the algorithm.
