Abstract
In this paper, the combination of SLM technique and BCM scheme is proposed to reduce the PAPR in a 16-QAM OFDM system. Four binary Reed-Muller codes are used as the BCM component codes to construct a 16-QAM OFDM code, which is then decomposed into the direct sum of a correcting subcode for encoding information bits and a scrambling subcode for encoding PAPR bits. Different scrambling subcodes in natural and cyclic ordering are considered respectively. Simulation results show that some scrambling subcodes of the proposed scheme achieve good performance in PAPR reduction than the conventional SLM.
