Abstract :
This paper develops a robust method to enumerate the incident signals impinging on a uniform but variable size linear array independent of their extent of correlation in a Rayleigh flat fading channel environment. The method also optimizes by minimizing the number of antennas to the number of signals and adapts continuously to maintain optimum performance in a mobile environment where users (signals) come and go. The technique is a modification of the matrix decomposition method of J.H. Cozzens and M.J. Sousa (see IEEE Transactions on Signal Processing, vol.42, no.2, p.304-17, 1994). A new set of stability, stopping and adaptive control criteria is presented. An algorithm is formulated with simulation and field results presented
