In adaptive beamforming,due to the mismatch of signal of interest( SOI) steering vector( SV),inefficiency of training data and the presence of the SOI components in the training data,the performance of classical beamformers may be considerably degraded. To deal with these problems,a robust beamforming method is proposed in this paper. Firstly,the MUSIC algorithm and parametric estimate are used to reconstruct the interference-plus-noise covariance matrix which does not contain SOI. With the constructed inte...
