Abstract :
This paper proposes a simple method to evaluate the average error probability for adaptive antenna array receivers in DS/CDMA systems. Adaptive array can reduce the interference only when the direction of arrivals (DOAs) of the interferers are misaligned (out-beam interferers) with the DOAs of the user of interest. The DOAs let the interferers be partitioned into two equivalence classes according to the beampattern, in-beam and out-beam interferers being counted differently in average error probability evaluation. For propagation over Rayleigh channels the model shows good agreement with simulation results
