BER performance of smart antenna systems operating over Rayleigh fading channels

Adaptive antenna arrays have shown real promise for substantial capacity enhancement of increasing the coverage range and capacity of base stations by directing beam patterns towards the desired signals and null-patterns towards the interferers in third generation (3G) mobile systems. This paper investigates a simple method to evaluate the probability of error in DS-CDMA receivers using a beamformer. This model can be employed to evaluate the average performance for 2D-Rake receivers over frequency selective Rayleigh fading channels.
