Abstract

In this paper, the performance of two FFH-CDMA multirate schemes are studied and compared. The first one is the classical variable processing gain fast frequency hopping CDMA (VPG FFH-CDMA) and the second is the newly proposed overlapped fast frequency hopping CDMA (OFFH-CDMA). Specifically, we analyze the signal to interference ratio for the VPG FFH-CDMA and the OFFH-CDMA systems. The bit error rate for the two systems is shown in the numerical results. We show that the newly proposed OFFH-CDMA always outperforms the classical VPG FFH-CDMA for different system scenarios.
