Abstract :
A RAKE receiver is found not useful in an OCC-CDMA system based on orthogonal complementary codes, and thus other alternatives have to be found to replace RAKE for signal detection in multipath channels. Thus, a pilot-aided detection scheme is introduced, particularly for its application in an OCC-CDMA system. Simulation results show that the scheme works well for an OCC-CDMA system under multipath interference.
