| 摘 要： | 最小均方误差(LMS)算法是自适应信号处理中最常用的算法.本文在给出LMS算法的原理的基础上,设计了一种单一频率的自适应陷波器的仿真方案.采用SystemView通信系统仿真工具,仿真了该自适应陷波器工作过程,给出了各点工作波形,并通过实验给出了不同参数条件下的陷波器收敛性能.实验结果表明,在合适的参数条件下,LMS算法可以兼顾收敛速度和稳态误差两方面的性能,实现性能良好的陷波器.同时,由于采用迭代算法,LMS算法更适合DSP或FPGA的数字实现.

| Abstract: | Least Mean Square(LMS) algorithm is one of the most popular adaptive signal processing algorithms.Based on the introduction of principle of LMS algorithm,this paper gives a design scheme of a single frequency notch adaptive filter,and simulates its working procedure by using the SystemView simulation tool.In this simulation,all signal waveforms are shown,and performances of the notch filter under different conditions are presented.The simulation results indicate that LMS algorithm can reach good performance... |
