卷积码的编码和VB译码
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. The generating polynomial of encoder is: [1 01; 11 1]. The output of the encoder through a Gauss white noise channel as a result of the decoder input, compare the output of the decoder and encoder input, understand the fault tolerance of convolutional code, and calculate the decoding results of bit error rate.)
