Abstract :
OFDM (orthogonal frequency division multiplexing) is an attractive technique for wireless high-bit-rate transmission due to the minimizing effects of frequency-selective fading and its high bandwidth efficiency. But OFDM has the high peak-to-average power ratio. In order to enhance the quality of transmission, there are many methods of reducing the PAPR value of OFDM system. The most recently, method of PTS and method of clipping can significantly improved OFDM system PAPR performance, but they all have shortcoming respectively. Therefore, a method of restraining clipping noise that combines with PTS is put forward. The simulation result shows that BER performance is improved in comparison with the traditional method of clipping or PTS and computational complexity is reduced.
