摘要：

This paper is concerned with the performance analysis of a Single Code Superposition Coded Modulation Orthogonal Frequency Division Multiplexing (SC-SCM-OFDM) communication system. A simple Chip-By-Chip (CBC) iterative Multi User Detection (MUD) strategy is used in SC-SCM-OFDM system. The performance of SC-SCM-OFDM has been studied over Additive White Gaussian Noise (A WGN), Jack fading and Rician channels using Saleh model as a High Power Amplifier (HPA). The goal of this paper is to reduce the number of the encoders and decoders for low design complexity and low bit error degradation. In case of double layer, the performance of Multi Code SCM-OFDM is better than the SC-SCM-OFDM system by only 0. 5 dB. For complexity analysis, the multi code system uses two encoders and two decoders while for the single code system, only one encoder and one decoder are used. Finally, the single code SCM-OFDM complexity is 50% better than multi code SCM-OFDM.
