| Abstract: | The paper first introduces the selected mapping method for the reduction of the peak-to-average power ratio of OFDM signals, and a method for improving SLM using m-sequence is put forward. The simulation result indicates that the method can greatly reduce the PAPR of OFDM system and, due to the characteristics of the m sequence, the improved OFDM system can be implemented easily without complex IFFT operation. |
