信号综合法通道均衡器的研究

Research of Channel Equalized by Signals Synthesis

以恢复理想信号为目的给出了频域和时域均衡的两种均衡器方案。首先分析了线性调频信号主／旁的理论特性和失真对它的影响，随后给出了用综合法确定通道均衡器特性的方法和实现方案，最后给出了通道内和通道间均衡的仿真结果。两种均衡方案仿真均给出了与理论特性一致的结果。

Two schemes to realize the equalizer in frequency and time domain in purpose of recov-ering the ideal signal are demonstrated,First,the theoretical performances of linear frequency--medulated signal and the effects on it by distortion are analysed. Then,the methods,to figure out channel equalizer’s performance and relevant scheme are discussed. Finally,the simulation of equalizing in channeis and among channels are carried out,the two methods both give satisfying results which correspond with the theoretical performance
