Abstract :
The performance of an asynchronous multi-cell direct-sequence code division multiple-access (DS/CDMA) system is evaluated in lineal microcells with shadowed Rician fading. The average bit error rate (BER) and the outage probability of the system are the performance measures of interest. Both binary phase shift keying (BPSK) and differential phase shift keying (DPSK) modulation schemes are considered. The effect of using macro-selection diversity to reduce the other-cell interference is studied. The impact of the Rician factor on the performance is also addressed
