| Abstract: | Selected mapping of reduction of PAPR in OFDM system is studied. A improved technique that can reduce computational complexity named TR-SLM technique, based on traditional, is proposed. Traditional and improved SLM scheme are simulated by MATLAB. And their influences on PAPR performance and computational complexity for system are analyzed. The results indicate that PAPR can be bated by the latter perfectly. |
