Abstract :
A new model is proposed for the analysis of CDMA systems. This model is a birth and death process whose birth process considers the new call arrival rate, the blocking rate, the effect of soft handoff and the effect of the band allocation strategy in multiband (multicarrier) CDMA systems. This model accurately predicts the distribution of the number of calls connected to a base station
