matlab信号处理，很详细的一本书，希望对你们有所帮助(matlab signal processing, a very detailed book, want to help you)

二用户CDMA系统，信道为加性高斯信道，使用BPSK调制，15位M序列扩频，可以正确解扩解调。 输出为2用户的基带信号、扩频信号、PSK调制信号、解调信号的时域和频域特性，给出两个用户分别的误码率。 (Second, the user CDMA system, channel for the additive Gaussian channel, using BPSK modulation, 15 M Sequence Spread Spectrum, you can correct demodulation despreading. Output of 2 user' s baseband signal, spread spectrum signal, PSK signal modulation, demodulation signal time domain and frequency domain characteristics of the two users are given the bit error rate, respectively.)

low pass filtering to remove noise

AHP层次分析模型，简介明了，可以直接带入数据，值得拥有！(AHP analytic hierarchy model, introduction and clear, can be directly to the data, is worth having! )

simple code for rotating spinor in the bloch sphere . Not that great . Used quaternion to do the job.

旅行商问题（Travelling Salesman Problem, 简记TSP):假设有一个旅行商人要拜访n个城市，他必须选择所要走的路径，路经的限制是每个城市只能拜访一次，而且最后要回到原来出发的城市。路径的选择目标是要求得的路径路程为所有路径之中的最小值。 此处使用蚁群算法求解TSP问题(Suppose a business trip to visit n cities, he must choose the path to go, pass through the restriction is to visit each city only once, and finally go back to the original departure city. Path selection objective is to get the path distance to the minimum value among all paths.Here,we use the procedure of ant colony algorithm to work out the TSP.)

说明：  matlab程序设计。对初学者很有帮助，非常容易理解。(matlab programming. Very helpful for beginners, very easy to understand.)

说明：  用于无线通信中天线仿真，matlab上的源代码，第六部分。(For wireless communications antenna simulation, matlab on the source code, Part VI.)

这是MATLAB的界面—GUI的几个例子，直接打开就能用。(This is the MATLAB interface- GUI examples, can be used to open directly.)

This model is very much useful in converting the normal three phase voltages to the corresponding alpha beta components
