- W2097942973 abstract "As orthogonal frequency division multiplexing (OFDM) has the advantage of anti-fading, high spectrum efficiency, low error rate, etc, it has been used more and more in wireless communication system. However, OFDM has the drawback of high peak-to-average power ratio (PAPR), thus how to reduce PAPR effectively is becoming a research hotspot. Although the random phase sequences generated by traditional selected mapping (SLM) scheme have good performance, they need to transmit much side information which increases the complexity of the system. An improved SLM method, whose random phase sequences produced by three-dimensional chaotic sequences, is proposed to reduce side information largely. The phase sequences can be acquired at receiving terminal by transmitting only an initial value and three parameters. Experimental results show that the PAPR performance of the system gotten by this method is better than that of traditional SLM obviously." @default.
