Abstract

The performance of a concatenated successive cancellation scheme for CDMA up-link transmission in cellular mobile radio is presented. Both serial and parallel cancellation stages are employed. Analysis and simulation results in flat Rayleigh fading asynchronous channels with both perfect and imperfect channel estimation, and with perfect ranking, indicate the accuracy of our analytical model. The concatenated scheme has the potential to reach the single user performance bound for up to K=120 users when the processing gain is 127 and one serial and three parallel cancellation stages are used
