由matlab编写,带GUI界面。对bmp文件进行Vector Quantization。运行其中的VQ_GUI.m文件。
程序肯定是调试无误的。虽然比较耗时,但是最后能达到较好的图像效果和SNR。毕竟相比于VC,matlab运行较慢。
注意在点open打开了一个bmp文件过后,一定要先点VQ code,进行其他操作才能有效。-prepared by Matlab, with GUI interface. Bmp files to Vector Quantization. VQ_GUI.

课程设计两个程序:一:数据帧(程序每帧设置为400bit)在有扰信道传输时,采用Turbo码进行编译码。并仿真Log-MAP译码算法在不同迭代次数下的性能。
二:实现有扰信道中,不同信噪比下,采用MAP译码算法的Turbo码的性能。
以上各主程序均有做比较详细的程序注释
可直接运行turbo_main.m或LogMAP.m,稍等片刻即可观察到仿真结果

LDPC码是通过校验矩阵定义的一类线性码,为使译码可行,在码长较长时需要校验矩阵满足“稀疏性”,即校验矩阵中1的密度比较低,也就是要求校验矩阵中1的个数远小于0的个数,并且码长越长,密度就要越低。
