Abstract:
High peak-to-average power ratio has been major issue in the implementation of orthogonal frequency division multiplexing systems in low cost application devices. In this paper, we propose an peak-toaverage- ratio reduction technique which uses channel coding especially expurgated codes. This method combines the error correction capability of the channel encoder and it achieves PAPR reduction in the OFDM system. Our technique is easily implemented in terms of encoding as well as decoding. We shall discuss the trade-o?s involved in our method.
