摘　　要：重点讨论了降低峰值平均功率比的BERC算法,并把该算法与剪波法进行了比较,仿真结果表明把OFDM和该算法结合可以有效克服OFDM系统峰平比过高的问题,使OFDM调制技术成为未来无线通信技术的首选。The principle and performance of OFDM technology are briefly discussed in this Paper. The paper formulates the BERC algorithm on reducing the peak - to - average power ratio of OFDM signal, which is followed by a comparison between BERC algorithm and clipping one. The simulation results show that the combination of OFDM and BERC algorithm can overcome the drawback of OFDM signal, and thus OFDM can be more suitable as a modulation scheme for future radio systems.
