A handset adaptive array antenna for the reduction of multipath co-channel interference in a realistic talking situation

摘要

This paper investigates the performance of adaptive array antennas in digital handset systems by studying the minimum mean square error (MMSE) algorithm at 2 GHz. The study shows that the adaptive array under consideration has substantial potential to not only reduce the relative power of interference signals, but also to combat multipath fading of the desired signal by using the space-diversity function of the MMSE, even in close proximity of a human operator.
