Abstract:

The digital communication system plays an important role as a forward error correction technology convolutional code.And the message receiver has a higher requirement on the decoding of the convolutional code.This article comes up with a simulation scheme of convolutional code's decoding with Matlab,and realizes the convolutional decoding with Viterbi Decoding.The simulation indicates that viterbi decoding is a perfect means for convolutional code's decoding,and it provides a good reference for technical applications.
