说明：  MATLAB 最新的时频分析工具箱1，里面包含大量的MATLAB时频分析函数(The latest MATLAB toolbox 1 time-frequency analysis, which contains a large number of time-frequency analysis of the MATLAB function)

这是一个最基本的OFDM系统仿真，说明一个信号通过OFDM系统所产生信号对比(This is a basic OFDM system simulation, that a signal generated by the signal OFDM system comparison)

可以计算物理学中的voigt线型，通过两个展宽的卷积实现更接近实际情况(this code could get the voigt of broad )

The following code implements a kernel wiener filter algorithm in MATLAB.The algorithm dependes on the eigenvalue decomposition, thus only a few thousand of data samples for training dataset is applicable so far.

获取图像上的曲线数据，读入一幅图片并选取所需的数据点加以保存处理。用法：使用鼠标左键取点，右键结束取点并保存数据(Get the curve on the image data, read and select a picture to save the data points needed to deal with. Usage: Use the left mouse button to take point, right end of the access point and save the data)

抑制载波双边带调幅和解调的实现, Matlab代码编写实现. 采用Matlab或者其它软件工具实现对信号进行抑制载波双边带调幅（DSB-SC）和解调，并且绘制： （1）信号 及其频谱； （2）载波 ； （3）DSB-SC调制信号及其频谱； （4）DSB-SC调制信号的功率谱密度； （5）相干解调后的信号波形。 (Carrier suppression bilateral with the realization of amplitude modulation and demodulation, Matlab code prepared to achieve. Using Matlab or other software tools to achieve suppression of signals with carrier bilateral AM (DSB-SC) and demodulation, and mapping: (1) signal and its spectrum ( 2) Carrier (3) DSB-SC modulated signal and its spectrum (4) DSB-SC modulation signal power spectral density (5) coherent demodulation signal waveform.)

说明：  对CDMA系统进行分析编程测试，通过本程序可以了解CDMA系统以及matlab的编程方法(Analysis of CDMA systems testing program, through this program can understand the CDMA system and the programming method matlab)

说明：  设计滤波器：设定10个零点，计算出多项式系数，作为滤波器系数； 取出绝对值较大的一半零点，重新设计滤波器；用剩下的绝对值较小的一半零点，重新设计滤波器。(Design a filter: Set of 10 zeros, calculate the polynomial coefficients as filter coefficients remove the larger half of the absolute value of zero, re-design filter with the remaining half of the smaller absolute zero, re-design filter.)
