Abstract :
The performance of an M-branch space diversity receiver with finite-length fractionally-spaced digital equalisers, designed to operate in a cellular mobile environment with frequency selective fading channels and co-channel interference (CCI), is investigated. Ideal channel-state-information is used to optimise the receiver for minimum mean-square-error (MMSE) at the output of the branch combiner. Simulation is used to obtain performance curves showing the influence of diversity and equaliser length on outage probability and average bit-error-rate. It is found that a receiver with equalisers of length 20 closely approximates the optimum linear receiver. Also, increasing the diversity gives a greater improvement than increasing the number of taps per branch
