Abstract :
Performance of beamspace MUSIC (BMUSIC) deteriorates as the coherent arrivals become closely spaced. In this paper, we improve the BMUSIC by using the forward-backward averaging of a combined signal eigenvectors. Evaluations are given to illustrate the proposed method capability. Performance analysis of the BPSK and QPSK modulation with antenna arrays are derived and compared to bit error rates (BERs)
