摘要 分析了线性失真对OFDM传输信号质量的影响。结合数字调幅广播(DRM)系统,分别对相位和幅度的线性失真作了具体分析和仿真,提出了DRM系统滤波器设计的指标要求。 This paper analyses the effect of linear distortion on OFDM signal. Based on DRM system, linear distortion of phase and amplitude is analyzed and simulated respectively, and the target of filter design in the DRM system is also given.
