|Abstract:||A DS/CDMA system may use multiple chip rate to support multi-data rate services and provide extra divisions among users. The technique is called `code & chip rate division multiple access (C2RDMA)' and its BER performance for a two-chip rates system is analyzed. Two methods (using co-channel interference Bernoulli model and Gaussian approximation) are compared. The results show that C2RDMA performs well for both small and large sized systems, particularly when a parallel correlator is employed for the lower chip-rate receivers. Various spreading code families such as M-sequence, Gold/Gold-like code, Kasami code and Walsh code are compared as well.|
