A Pre-Interleaver and Error Control Based Selective Mapping Method for PMEPR Reduction in MC-CDMA

Sajjad A. Memon, Zhe Chen, and Fuliang Yin
Abstract— The multi-carrier transmission signal in MC-CDMA has a high Peak-to-Mean Envelope Power Ratio (PMEPR) which results in nonlinear distortion and system performance degradation. To reduce PMEPR, a pre-interleaver and error control coding based selective mapping method is proposed in this paper. This method generates 2n sequences of the original data sequence via adding n PMEPR control bits to the original data followed by an interleaver and error control code to make original data more random. The covolutional codes, cyclic codes and low density parity check (LDPC) codes are used as error control codes. The proposed method achieves significant PMEPR reduction and avoids the need of side information transmission. The simulation results reveal the validity of proposed method.

Index Terms— MC-CDMA, peak to average power ratio (PAPR), high power amplifier (HPA), selective mapping.
