CAPACITY OF CDMA FOR INTEGRATED TRAFFIC IN DIFFERENT WIRELESS ENVIRONMENT

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, we introduced an admission control algorithm. Under this algorithm, the capacity of a CDMA system for integrated traffics is evaluted. 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, we derived the capacity of different traffics in different environments.
