说明：  MATLAB的中文帮助文档，让那些不愿意看英文的朋友们，简单明了的学习MATLAB(MATLAB help documentation in Chinese, English, for those who do not want to see friends, to learn simple MATLAB)

SAP，ABAP编程，利用SMARTFORM生成PFD文档并通过EMAIL发送(SAP, ABAP programming, using SMARTFORM to generate PFD documents and sent by EMAIL)

基本粒子滤波器的实现,对非线性非高斯目标可进行有效跟踪!(elementary particle filter to the realization of non-Gaussian nonlinear objectives can be effectively tracking!)

 产生长度为1000的标准正太分布的随机信号，画出时域波形及频谱；  采用u=255的非均匀PCM编码，每符号为8bit，画输入-输出关系图；  计算信号量化噪声比（SQNR）；  信道误码率为10-3；  解码，并画出u律反变换后的信号时域波形及频谱。 扩展要求：  采用均匀PCM、量化级数可变、信道误码率可变。 ( have a standard length of 1000 is too random signal distribution, draw time-domain waveform and frequency spectrum  u = 255 using the non-uniform PCM encoding, each symbol for 8bit, drawing input- output relationship diagram  calculated quantization noise signal than (SQNR)  channel bit error rate of 10-3  decoder, and law to draw u the signal after the inverse transform time-domain waveform and frequency spectrum. Expansion of the requirements:  uniform PCM, quantization level variable, a variable channel bit error rate.)

matlab小波图像去噪程序,利用小波变换去除图像中的噪声(matlab wavelet image denoising procedure)

SAR成像，使用的是经典的距离多普勒算法，用c++形成矩阵，然后可以在matlab上看到图像(SAR imaging, using the classic distance Doppler algorithm using c++ form a matrix, then you can see an image in matlab)

这个是对各种信道，如awgn、rayleigh、rice等的一个仿真。简单易懂，意义较大(This is a variety of channels, such as awgn, rayleigh, rice, etc. a simulation. Easy to understand, the larger significance)
