（2，1，9）VB译码器Verilog代码

二维码的VB程序实现，包括编码程序和译码程序，可用于二维码二次开发，源码值得学习。-VB program to achieve two-dimensional code, including the encoder and decoder program can be used for the secondary development of two-dimensional code, source code is worth studying.

该程序能实现球形译码算法，分别针对不同搜索策略，即CL和VB策略-The program can achieve sphere decoding algorithm, respectively, for different search strategies, namely CL and SE strategy

在MATLAB上设计一个（2，1，3）卷积编码器和对应的采用维特比译码算法的译码器。编码器的生成多项式为：[1 0 1；1 1 1]。将编码器的输出经过一个高斯白噪声信道的结果作为译码器的输入，观察比较译码器输出和编码器输入，了解卷积码的容错性，并计算译码结果的误比特率.(A convolutional coder (2, 1, 3) and corresponding decoder using Vitby decoding algorithm are designed on MATLAB.
