Abstract
To settle the issues that peak to average power ratio (PAPR) in OFDM systems are too high, the paper proposes a fresh algorithm of reducing PAPR by using the improved selected mapping (SLM) and extended hamming codes. Our combining strategy can be used for both error correction (EC) and PAPR reductions. The transmitted OFDM signals are selected which achieves minimum PAPR, from the set of extended hamming codes. The received signal can be decoded with no need of any side information, and EC function helps to reduce the bit error rate (BER). Both the theoretical analysis and simulation results prove that this novel method can successfully reduce PAPR in OFDM system, in the meantime, the system has good performance of BER simultaneously.
