Abstract :
Multiple chip rates can be applied to a DS/CDMA system in order to enhance the potential system capacity which otherwise is limited by the spreading code family size. The technique is called “chip rate division access” (CRDMA). A co-channel interference method based on cross-correlation statistics is used to study the performance of the CRDMA with various spreading code families
