Enhanced adaptive array performance via DOA detection

In various communications-based adaptive array applications, the directions of arrival (DOAs) of the desired user signal are sparsely separated. As such, the desired beam-pattern has a sparse structure. We propose an NLMS-based adaptive algorithm which exploits this sparse DOA structure and provides significantly improved convergence speeds.
