传统的宽带信号中抑制正弦干扰的方法是采用陷波器(notch filter),为此需要精确知道干扰正弦的频率.然而当干扰正弦频率是缓慢变化时,且选频率特性要求十分尖锐时,则最好采用自适应噪声抵消的方法.下图是用一个二阶FIR的LMS自适应滤波器消除正弦干扰的一个方案。该代码实现了以下功能:
1) 借助MATLAB画出了滤波器的误差性能曲面和误差性能曲面的等值曲线;
2) 给出了最陡下降法以及LMS算法的计算公式;
3) 用MATLAB产生了方差为0.05, 均值为0白噪音S(n),并画出某次采样得到的波形;
4) 根据 2)中的公式,并利用 3)中产生的S(n),在 1)中的误差性能曲面的等值曲线上叠加画出了采用最陡下降法以及LMS法时H(n)的在叠代过程中的轨迹曲线;
5)用MATLAB计算并画出了LMS法时误差随时间n的变化曲线(对应S(n)的某一次的一次实现)和e(n)波形;
6)在 1)中的误差性能曲面的等值曲线上,叠加画出采用LMS法得到的100次实验中的H(n)的平均值的轨迹曲线;
7)最终对结果进行了分析,具体见压缩包的word文档。
