Abstract :
Computing the eigenvalue decomposition (EVD) of a symmetric matrix is a frequently encountered problem in adaptive (or smart or software) antenna signal processing, for example, super resolution DOA (direction of arrival) estimation algorithms such as MUSIC (multiple signal classification) and ESPRIT (estimation of signal parameters via rotational invariance technique). In this paper the hardware architecture of the fast EVD processor of a symmetric correlation matrix for the application of an adaptive antenna technology such as DOA estimation is proposed and the basic idea is also presented.
