matlab入门经典教程--百看不厌，详细讲解matlab入门的基本知识(Introduction to Classical matlab tutorial- never get tired)

基于有限混合高斯模型的数据分类 1、使用基于有限高斯混合模型的EM算法对数据样本进行归类 2、使用C++或者Matlab语言编程环境实现该算法，并用给定的数据包对算法的正确性进行检验 (Gaussian mixture model based on limited data classification 1, using the finite Gaussian mixture model based on EM algorithm to classify the data samples 2, using the C++ or Matlab programming environment to realize the algorithm, and with a given data packet to the algorithm correctness testing )

一个用matlab编的可以动的飞机动画制作小程序（源程序在网上下载，经本人稍加改动），注意六个状态值是需要外部输入的，比较适合做飞行器仿真试验用。(a series of the aircraft can move small animation (downloaded from the Internet source, I is modified), to six state value is a need for external input, more suitable for aircraft simulation experiment.)

最优化技术方法介绍及MATLAB的实现（科学工业出版社）(MATLAB optimization method)

通信系统中，无线物理层的QPSK调制解调技术。(Communication systems, wireless physical layer of the QPSK modulation and demodulation technology.)

this is a MPSK mudulation with BER and PSD .

该模型是模拟信号数字传输系统，可以把一个模拟信号通过PCM编码译码，信道2FSK编码译码，再通过一个二进制对称信道，可以恢复出原模拟信号(The model is the analog signal digital transmission system, an analog signal by the PCM codec, channel 2FSK codec, and then through a binary symmetric channel, you can restore the original analog signal)
