说明：  QPSK仿真，通过高斯信道，瑞利信道进行调制解调，计算误码率，绘制星座图(QPSK simulation, through the Gaussian channel, Rayleigh channel modulation and demodulation, calculate the bit error rate, draw constellation)

step pid with avr mikrokontroller

混沌时间序列cc方法重构相空间，很好的方法(Chaotic time series phase space reconstructed cc, good way)

可以实现对字符或txt文件内容进行Huffman编码(A matlab program that can be achieved for character or content of Huffman coding txt file)

《Digital and Analog Communications Systems》（《数字和模拟通信系统》）的配套MATLAB源代码，该书对数字和模拟通信系统都有讲述，偏重于数字通信系统。("Digital and Analog Communications Syste ms "(" digital and analog communications system ") supporting MATLAB source code, The book on digital and analog communications systems have talked about emphasis on digital communications systems.)

matlab 将以综合了matlab的各种功能，有很大的用处！！(matlab matlab will combine the various functions is very useful! !)

LBG算法，初始码本随机给出，然后根据对训练矢量的划分，计算形心，更新码本。原代码中含有去空胞腔的程序。(LBG algorithm, given a random initial codebook, and then based on the division of the training vector, computing the centroid, update this code. Contains the original code to empty cell process.)

说明：  用matlab编写的fft快速傅立叶变换及逆变换函数,文件用M语言写成，可以运行(Matlab prepared using fft Fast Fourier Transform and inverse transform function, M language documents, you can run)
