Abstract: Coherence is often encountered in sonar, radar or mobile communications. Performance of beamspace MUSIC (MUltiple Signal Classification) deteriorates as the coherent arrivals become closely space. An improvement for beamspace MUSIC resolution is presented. Decorrelation as a preprocessing is performed by two techniques called forward-backward spatial smoothing and combined signal eigenvector. Evaluations are given to illustrate the capability of the proposed method to distinguish closely space directions and reduce estimation errors in the presence of fully correlation. Performance analysis of BPSK and QPSK modulations are derived and compared with the simulation results.
