Abstract :
In this paper we derive asymptotic performance measures for multiuser receivers in multi-carrier CDMA communication systems. We consider both single-code-per-user and multi-code cases. Specifically, we derive the asymptotic average SINR and BER at the output of a multiuser LMMSE receiver. Simulation studies demonstrate that the asymptotic results closely predict performance of practical finite systems.
