Match filter bound analysis used to evaluate range increase provided by an adaptive antenna array

An analytical approach is developed for evaluating the expected range increase and variations in coverage range, while using an M-element adaptive antenna array at the base station (BS). The analysis is based on the match filter bound an the bit error rate probability for a frequency non-selective Rayleigh fading channel. Results for a ten element uniform linear array (ULA) indicate the expected range increase over a BS with only a single antenna can be nearly doubled. A 1.6 to 1.7 increase is also likely with a five-element array.
