摘　　要：针对正交频分复用信号包络波动过大,导致信号传输过程中频谱扩散和非线性失真,文章提出基于维纳维纳滤波器的正交频分复用系统滤波方法。该方法首先分析了正交频分复用的包络波动和误比特率特性,然后采用维纳滤波对正交频分复用的立方度量进行抑制。仿真结果表明,该方法能够灵活抑制信号包络大小和误比特率,可满足系统对于信号质量的要求。Aim at the excessive envelope fluctuations of orthogonal frequency division multiplexing signals,which lead to spectral spread and non-linear distortion in the signal transmission process,a filtering method based on the Wiener filter was proposed.The method first analyses the envelope fluctuation and false bit rate characteristics of orthogonal frequency division multiplexing,and then uses the Wiener filter to suppress the cubic metric.The test results show that the method can flexibly suppress the signal envelope size and false bit rate,which meets the quality by signal transmission.
