Blind DOA Estimation Based on JADE Algorithm in Multi-path Environment

In this paper, we consider the problem of direction-of-arrival (DOA) estimation in the presence of multi-path propagation. The sensor elements are assumed to be linear and uniformly spaced. To solve this problem, we propose a two step approach to perform DOA estimation in the presence of coherent signals for a uniformly spaced linear array of sensors. First, the effective steering vectors are estimated using the JADE algorithm. Then, the modified forward-backward linear prediction (MFBLP) algorithm estimates the DOA using the estimated vectors. We summarize the algorithms herein and present Monte-Carlo simulations demonstrating the effectiveness of the new algorithm.
