Abstract

We propose an improved fast algorithm for spatial signature estimation in array antenna systems. We provide an analysis for a fast estimation algorithm, which is not fully exploited in the previous work of Kim and Xu (see Proc. of IEEE Vehicular Technology Conference, 1997). Based on the analysis, we derive an improved algorithm which yields more accurate estimates with tolerable increment of computational complexity. The improvement is accomplished by compensation of noise power. Two different estimation methods for the noise power are presented. We investigate the performance of the proposed method via computer simulation
