连续小波变换：小波函数与原信号对应点相乘，再相加，得到对应点的小波变换系数，平移小波基函数，再计算小波函数与原信号对应点相乘，再相加，这样就得到一系列的小波系数。对于离散小波变换（由于很多小波函数不是正交函数，因此需要一个尺度函数）所以，原信号函数可以分解成尺度函数和小波函数的线性组合，在这个函数中，尺度函数产生低频部分，小波函数产生高频部分。(Continuous wavelet transform: a series of wavelet coefficients are obtained by multiplying and adding the corresponding points of the original signal, translating the wavelet basis function, and calculating and adding the corresponding points of the original signal. For discrete wavelet transform (many wavelet functions are not orthogonal functions, so a scale function is required), the original signal function can be decomposed into a linear combination of scale function and wavelet function, in which the scale function generates the low frequency part and the wavelet function generates the high frequency part.)

BER
这是一个matlab和optisystem联合调试用的误码率计算程序，里面的文件报过一个可以用optisystem7和optisystem13可以打开的OSD仿真图，还有一个MATLAB计算BER的程序。给出了如何设置系统的大纲。从OptiSystem的电信号输入到Matlab组件。当OptiSystem运行时，它将调用Matlab组件中的M文件，处理数据，然后将所得的电信号导出回OptiSystem。然后将输出信号连接到BER分析仪。经过我调试，文件齐全，放心下载(The attached image gives an outline of how the system should be setup. You should start with inputting the electrical signal from OptiSystem into a Matlab component. When OptiSystem runs, it will call the M-file in the Matlab component, process the data, and then export the resulting electrical signal back into OptiSystem.The output signal is then connected to the BER Analyzer.)
