This is a MATLAB code which returns the adjacency matrix of a weighted graph.

说明：  如题，关于HHT变换的三种方法，是目前最全的。(The three methods of HHT transformation are the most complete at present.)

用自适应法做时延估计，然后根据时延估计确定声源的定位(Adaptive time delay estimation method used to do, and then determine the time delay estimation based on the positioning of the sound source)

基于matlab平台的编程 实现pcm 编码的功能(the file is based on the matlab and it has the function of pcmcoding )

说明：  经典功率谱估计welch例子，可以用于入门学习。(Welch classic example of the power spectrum estimation, can be used for getting started.)

自己写的一个车牌定位matlab程序，希望对大家有用。(Himself wrote a matlab license plate location process, in the hope that useful to everyone.)

利用M函数仿真扩频通信系统。6个用户的CDMA的同步通信系统，每个用户利用L＝31的Gold码，进行扩频，信道为AWGN信道，接收端利用匹配滤波器进行检测。绘出当N＝10000个发射比特下，SNR＝0：15（dB）时的误码率曲线。 (M function simulation using Spread Spectrum Communication System. 6 simultaneous users of CDMA communication system, each user of the L = 31 the use of Gold codes for spread spectrum, channel for the AWGN channel, the receiving end to detect the use of matched filter. Drawn when N = 10000 bits of transmission, SNR = 0:15 (dB) when the bit error rate curve.)

SAR成像很好的学习资料，希望大家喜欢。(The SAR imaging learning materials, hope you like)

matlab最常用，最实用的程序代码，初学者必须要掌握的。重要！！！(matlab most commonly used and most useful code, beginners need to master. Important! ! !)
