Abstract :
The bit error rate (BER) performance of the M-ary DS/CDMA cellular system in the presence of an additive white Gaussian noise (AWGN) and interference from other cells has been investigated. The data frame structure of the IS-95 system was adopted. The system operated in an asynchronous mode with perfect power control and voice activity factor of 3/8. Both the hard handoff and the soft handoff were considered respectively. A close form expression for the BER performance has been derived for the single cell CDMA system whereas numerical integration was employed for the multiple cells CDMA systems instead
