卷积编解码
说明: 使用Simulink(或m语言)仿真卷积编码,并用Viterbi译码的方法进行解码,其中的编码、译码全部是自己编写代码(m语言方式),不是调用Simulink(或m语言)的已有编码、译码函数。并在加性白高斯噪声信道中,画出比特信噪比与误码率的关系曲线。(Simulink (or M language) is used to simulate convolutional coding, and Viterbi decoding method is used to decode, in which the coding and decoding are all written by themselves (M language mode), rather than calling the existing coding and decoding functions of Simulink (or M language). In the additive white Gaussian noise channel, the relationship curve between bit SNR and BER is drawn.)
