In this paper, the authors propose a multi-code multi-carrier Code Division Multiple Access (CDMA) scheme for next generation wireless communication systems. This system retains the advantages of multi-carrier CDMA in combating multipath and rejecting interference, and provides variable and adaptive data rates through the use of multi-code scheme. The rate adaptation algorithm proposed computes the user data rate as a function of the instantaneous channel condition and application dependent data rates. Exploiting the channel information improves the effective data rate and overall capacity of the system.
