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

1. 均值滤波:即线性滤波,有: a.邻域平均, b. 加权平均两种。
a. 邻域平均:用一个像素邻域平均值作为滤波结果,此时滤波器模板的所系数都取1,为保证输出图仍在原来的灰度值范围,在算得R后要将其除以系数总个数再进行赋值,对3*3的模板来说,在算得R后要将其除以系数9。
b. 加权平均:对同一尺寸的模板,可对不同位置的系数采用不同的数值,一般认为离对应模板中心像素近的像素应对滤波结果又较大贡献,所以接近模板中心的系数可比较大而模板边界附近的系数应比较小。(1. mean filter
