设计一个2阶加权自适应噪声对消器，对经加性白高斯噪声信道干扰的正弦信号进行滤波。(Design a two-order-weighted adaptive noise canceller, right through the additive white Gaussian noise channel interference sinusoidal signal filtering.)

MATLAB设计简易计算器 运行通过,方便灵活(MATLAB simple calculator designed to run through, convenient and flexible)

说明：  本程序是一个采用背景差分的运动目标检测方法(This program is a moving target using the background difference detection method)

说明：  用matlab快速实现说话人识别中FFT，欢迎大家参考，用处很大哦(Fast Implementation matlab FFT Speaker Recognition)

说明：  常用函数的汇总，有利于日常编程使用，用到某个函数时，可以直接整段截取(Common function)

针对谐波检测问题，比较几种常用谐波检测方法，总结出各自的适用条件。结合经验模态分解理论和总体平均经验模态分解(empirical mode decomposition，EEMD)算法，提出基于EEMD的谐波检测方法。(For harmonic detection problem, comparing several common harmonic detection method, summed up their applicable conditions. Combining theoretical and empirical mode decomposition overall average empirical mode decomposition (empirical mode decomposition, EEMD) algorithm, based on harmonic detection method EEMD.)
