DOA Estimation of Multi-path Signals Using Transient Smoothing Method
Fugang Liu, Ming Diao · 2013
The present work introduces a novel algorithm for Direction-ofarrival (DOA) estimation of signals in the multi-path environment. The technique relies on transient smoothing way to extract the coherence properties of sub-array, and restores the rank of the data covariance matrix. After processed, the multipath channel signals were de-correlation and can be processed by traditional DOA estimation algorithms. Through extensive computer simulations, the relation between ratio of phase and position of signal sources has been demonstrated. The performance of technique is contrasted with other suggested methods in the different assumptions.
