PAPR-Reduction-of-OFDM

代码说明：

  OFDM系统降低峰均比方法的研究。在改进的SLM技术中提出了一种基于比较序列随机性的判决算法,采用 此算法可以在IFFT之前选择发送序列,从而只需要一个IFFT模块。通过仿真证明,这种判决算法可以在较小的计算量和复杂度条件下获得同原有SLM技术相同的降低峰均比性能。(Research on Peak?to?Average Power Ratio Reduction Scheme of OFDM Signal SLM(Selected mapping) is an effective algorithm for the reduction of peak?to?average power ratio(PAPR) ofOFDM(OrthogonalFrequeneyDivisionMultiplexing) signalwithoutdistortion. In genera,l SLM selects the transmitted sequencewithminimum PAPR after IFFT, so that the system needs some IFFTs operating in parallel and is very complex. An improved SLM technique, which adopts a simpler algorithm to select the transmitted sequence before IFFT by comparing randomness of sequences, is proposed.)
