sparfilt
优点:1.对于信噪比高的信号滤波效果好;
% 2.对于边沿的保护强过阈值滤波,不会产生阈值滤波情况下的过于平滑与Gibbs现象。
%缺点:1.由于对边沿信号没做任何处理,所以边沿可能会有脉冲噪声保留下来;
% 2.计算相关系数中,如果计算出来的小波系数点位置偏差大,则相关系数计算受影响;
% 3.需要迭代运算,迭代的噪声能量阈值选取很重要,这里以开始段无信号处估计噪声;
% 4.需要迭代运算,所以运算量比阈值法大;
% 5.受分解层次影响,在大尺度上小波系数点位置偏差更大,相关系数计算不准确。
%需要具体调整的地方:1.分解的尺度;()

说明: 把I、Q 两路信号分别作FFT ,找出频域内信号的幅度,即可算得两路分量的幅度一
%致性 把I、Q两路信号合成一个复数信号,作FFT ,对得到的频谱求镜像抑制比。(The I, Q signals, respectively, for the two FFT, to identify the range of frequency domain signal can be considered two-way range of 1 weight of the letter I, Q synthesis of two-way signal a plural signal for FFT, to obtain the spectrum for image rejection ratio.)
