<title>Generalized architecture for DOA estimation for wideband/narrowband sources</title>

Abstract

The high-resolution Direction-Of Arrival (DOA) estimation algorithms are studied to develop architecture for real time applications. Methods for DOA estimation for wideband sources proposed by Buckley and Griffiths' and MUSIC 2 algorithm for narrowband sources proposed by Schmidt2 have been selected for hardware implementation. These algorithms have been simplified and generalized into one common programmable algorithm. It is then parallelized and is executed in a pipelined fashion. A parallel architecture have been designed for this generalized algorithm.

Dynamic DOA estimation via locally competitive algorithm

“…Direction of Arrival (DOA) estimation plays a fundamental role in many applications involving radar [1], underwater sonar detection [2], cellular mobile communication [3], seismic sensing [4], satellite communications [5] and medical imaging [6]. The goal is to find the locations of the sources of wavefields which impinge on an array of sensors.…”
