DOA estimation in multipath based on third-order cyclic moment

Abstract A new direction of arrival (DOA) estimation algorithm in multipath based on third-order cyclic moment is proposed in this paper. The algorithm can highly solute every DOA in multipath, and the use of third-order cyclic moment suppresses all stationary measurement noises. The simulation shows the advantages of this algorithm.
