This program simulates the bit-error-rate (BER) performance of OSTBC with L=4 antennas over the frequency flat Rayleigh block fading channel The code is developed for real orthogonal design, code rate 1/2 modulation- 16 QAM with gray coding resulting in 2 bits/sec/Hz.(This program simulates the bit-error-rate (BER) performance of OSTBC with L = 4 antennas over the frequency flat Rayleigh block fading channel The code is developed for real orthogonal design, code rate 1/2 modulation-16 QAM with gray coding resulting in 2 bits/sec/Hz.)

多目标蚁群算法，蚁群算法(ant colony optimization, ACO)，又称蚂蚁算法，是一种用来在图中寻找优化路径的机率型算法。(MOACO，Multi-objective ant colony algorithm)

说明：  利用改进的蚁群算法来实现对路径规划，找到一条最优路径(Ant colony algorithm path planning)

这个程序实现了MPEG2的视频压缩，用于Internet上视频流的处理（IP流还没有实现），程序的注释相对比较少，所以可能比较难理解些。下载后请先看说明。(This program implements MPEG2 video compression, video streaming for the Internet, the processing (IP flow has not yet achieved), program notes relatively small, it may be more difficult to understand something. Please read download instructions.)

lear N = 10^5 EB_NO = [-1:30] liu1 = zeros(1,N) liu2 = zeros(1,N) for ii = 1:length(EB_NO) m= (2*(rand(1,N)>0.5)-1) + j*(2*(rand(1,N)>0.5)-1) s = (1/sqrt(2))*m normalization of energy to 1 n = 1/sqrt(2)*[randn(1,N) + j*randn(1,N)]

说明：  快速傅里叶变换FFT通用matlab源程序,众所周知，matlab工具箱里的fft函数是内置的，我们无法看到其源代码，为了学习交流方便，特帖出本人以前用matlab语言写的fft通用matlab源程序，以供初学者学习参考之用！(FFT fast Fourier transform common Matlab source, as we all know, the Matlab toolbox fft function is built-in, we can not see the source code, in order to facilitate the exchange of learning and special TIE out I used to write using the Matlab language fft common source Matlab, for beginners to learn reference only !)
