Abstract :
This paper studies the performance of adaptive array antennas in digital handset systems using the minimum mean square error (MMSE) algorithm at 2 GHz. Particular emphasis is placed on how well the handset adaptive array antenna works under practical conditions, involving multi-path radio wave propagation and the influence of the body of the user. A computer simulation was carried out in a flat Rayleigh fading environment with multiple co-channel interference signals, in which the average bit-error-rate (BER) of a handset adaptive array antenna was studied for the coherent detection of phase-shift keyed signals
