使用MATLAB实现卷积码的编译码，信源为随机产生数，进行软判决译码-Convolutional code using the MATLAB implementation of the codec, source for the randomly generated number, to soft-decision decoding

BPSK仿真在AWGN信道下产生卷积码和非卷积码的比较，约束长度7，多项式[171,133],码率1/2，分别采用硬判决和软判决,Convolutional code and convolutional code comparison, simulation BPSK in AWGN channel constraint length 7 polynomial [171,133], code rate 1/2, respectively, using the hard-decision and
