This thesis has proposed two systems: the RIM-OFDM system with diversity reception exploits simultaneously the frequency and spatial diversity to achieve better SEP performance than the conventional IM-OFDM with diversity reception; The RIM-OFDM system with CI attains higher reliability and flexibility than the conventional IM-OFDM-CI system. The low-complexity detectors were also proposed to reduce the complexity while still achieve nearly same performance of the ML detector.
