Abstract In the beamformer based on sample covariance matrix inverse (SMI) algorithm, the calculation of weight vector comprises the components of interferences and noise. The projection method comprises the components of interferences. It induces the imperfective results of the beamformer. Under the environments of high signal-to-noise ratio (SNR) and large steering error, SMI algorithm and the projection method are invalid. The cyclic beamformer of utilizing signal s cyclostationarity is proposed to resolve the problem above-mentioned. The simulation results verify the cyclic beamforming algorithm.
