Abstract

In this paper, interference power variation at a base station receiver in a CDMA system that supports integrated services is investigated. It is demonstrated that even under perfect power control conditions, the supporting of multi-rate/service users in shared channel will cause the interference power to vary significantly causing unpredicted delivery for services. Numerical results are presented in an integrated voice and data system. When the power factor (which is a function of bit rate and bit error rate) is increased from 1 to 10, the normalized standard deviation of interference power increases approximately 75% in a 12-sector cell under Poisson distribution of multimedia traffic.
