PHDIFF函数是matlab函数，用于寻找两个震荡子的相位差(Matlab function PHDIFF function is used to find find the phase difference between two oscillations.)

说明：  通过Monte Carlo仿真，说明DS扩频信号在抑制正弦干扰方面的有效性。用一均匀随机数发生器产生某个二进制信息符号的序列，每个信息比特重复Lc次。 包含文件：DS_restrain_interference.M SS.M(through Monte Carlo simulation, note DS spread spectrum signal sinusoidal interference in inhibiting the effectiveness. Using a uniform random number generator produce a binary sequence information symbols, each bit of information to repeat Lc times. Documents include : DS_restrain_interference.M SS.M)

此程序为测试窗函数宽度对时－频分辨率的影响，即测不准原理，对时间分辨率和频率分辨率只能取一个折中，一个提高了，另一个就必然要降低，反之亦然。(This procedure for the test window function width on- frequency resolution, that is, the uncertainty principle, the time resolution and frequency resolution can only take a compromise, an elevated, and the other is bound to reduce, and vice versa .)

It describes a stage of cotton flower whether it is matured or not.

通过设计一个二阶加权系数自适应横向FIR滤波器，对一个加随机噪声的正弦信号实现滤波。 具体设计方案为： 1，生成标准正弦信号S 2，生成等长的随机信号N 3，生成加随机噪声的正弦信号X 4，X通过参数可调数字滤波器，输出Y 5，Y与参考信号作差得到误差E 6，E通过自适应算法调整权值W 7，用LMS算法处理噪声干扰的信号，最终实现滤波器功能(A two order weighted coefficient adaptive transverse FIR filter is designed to filter a sinusoidal signal with random noise. The specific design scheme is as follows: 1, generating a standard sinusoidal signal S 2, generating an equal length random signal N 3, generating a sinusoidal signal X with random noise 4, X can adjust the digital filter by parameter and output Y 5, the difference between the Y and the reference signal is E 6, E adjusts the weight W through the adaptive algorithm 7, the LMS algorithm is used to deal with the noise interference signal, and the filter function is finally realized.)
