Abstract

A generalized covariance matrix computation processor has been designed. The covariance matrix is the first processing step for the computation of the direction of arrival (DOA) algorithms. This covariance processor is useful for computing the covariance matrix for various DOA algorithms. In this work three DOA algorithms namely MUSIC algorithm for narrowband signal and BASS-ALE & bilinear transformation algorithms for wideband signals have been considered. The processor has been implemented using 0.8 micron CMOS technology and is suitable for real time processing
