一种通信信道优化迭代均衡的新型算法

A New Algorithm for Iterative Equalization Communication Channel Optimization

信道估计与均衡是通信系统中接收端必不可少的部分,通过信道估计得到信道特性,然后用均衡器产生与信道相反的特性以恢复信号。本文介绍一种迭代均衡算法,并从复杂度和性能两个角度分别提出优化算法,然后给出仿真结果。最后,给出了复杂度与性能的差异对比。

Channel estimation and equalization are essential parts of the receiver in the communication systems,channel estimation is used to get the channel characteristics,and then equalizer is used to produce the opposite characteristics of the channel characteristics to recover the signal.We introduces an iterative equalization algorithm,and propose optimization algorithms from two perspectives:complexity and performance,and then provide the simulation results.At last,we provide a comparison of differences in complexity and performance.
