摘要
信道均衡技术是无线通信中解决码间干扰的关键技术。选取LMS,RLS和CMA常用的均衡算法以及信道均衡器的结构作为研究对象,通过对三种均衡算法的收敛性能的仿真分析,以及结合无人机信道模型对常用的两种均衡结构的误码性能进行的仿真,所得结果对于后期基于FPGA实现高速的信道均衡器时算法和结构的选择具有参考的价值。
Channel equalization is an essential technology of wireless communication to reduce the ISI.This paper choses LMS,RLS,CMA algorithms and structures difference of equalizer as study objects,using Matlab software doing simulation to compare the convergency of the three algorithms.The bit error rate of different structures equalizer was compared.The results of the simulation can be used to choose the proper algorithm and equalizer structure for the implementation of channel equalizer based on FPGA and other devices.
