A new model for the DOA estimation of the coherent signals
Liang Jin, Minli Yao, Qinye Yin · 2002
Based on the movement of the sources, a new model for the DOA estimating of the coherent signals is proposed herein, under which the signals and their multipath counterparts are decorrelated without spatial smoothing or spatial signature estimation, and the cyclic methods such as cyclic MUSIC and cyclic ESPRIT can be directly employed in the multipath scenarios. The signal selectivity and interference suppression can be achieved in practical mobile communication. The effectiveness of this new model is demonstrated by simulation results.
