摘要
针对短波通信信道中信号传输受到多径效应影响的问题,设计了一种基于变步长LMS算法的线性自适应均衡器,可以有效获得信道均衡的效果,最后通过仿真测试并在DSP上编程得以实现。
Aimed at the problem that the signal transmission would be effected by the muhipath effect in shortwave communication channels, this paper designs a linear adaptive equalizer based on a variable step size LMS algorithm. It could effectively obtain the effect of channel equalization. Finally, the simulation tests the performance in DSP programming.
