Abstract: To estimate DOA(Direction of Arrival) of wideband cyclostationary signals,a novel fast algorithm referred to as spectral correlation multi-stage Wiener filter(SC-MSWF) is presented in this paper.In virtue of combining the cyclostationarity theory and multi-stage Wiener filter theory,the presented algorithm does not need the focusing operations,and neither do need the estimation of the cyclic covariance matrix and its eigendecomposition.And thereby when it has all of the advantages of cyclic DOA estimation algorithms,it is computationally efficient.The simulation results demonstrate its effectiveness.
