摘要：

OFDM is a promising broadband technique. However, the implementation disadvantage of OFDM is high peak to average power ratio (PAPR). Selective Mapping (SLM) is an effective method for reducing PAPR in OFDM. The main drawback of this technique is that, it requires side information to he transmitted, which results in some data rate loss. A new modified technique based on SLM using convolution code without side information is presented in this paper. By considering, the example of OFDM with BPSK modulation, simulation results shows that this method performs well in reducing PAPR without the need of any side information.
