CAPACITY OF CDMA FOR INTEGRATED TRAFFIC IN DIFFERENT WIRELESS ENVIRONMENT
综合业务的CDMA系统在不同无线环境下的容量分析

The developments of personal communication and mobile computing stimulate the introducation of integrated traffics into mobile communication. CDMA is suitable for transmission of integrated traffics. In this paper, an admission control algorithm is introduced. Under this algorithm, the capacity of a CDMA system for integrated traffics is evaluated. Users with different QoS requirements are allocated different power. To solve the problem of higher-rate traffics using higher powers, wider bandwidth to higher-rate traffics is given. All the traffics are transmitted in the same frequency band. Finally, according to the measured data of CODIT, the capacities of different traffics in different environments are derived.
