Two novel interleaving schemes of the (2,1,3) convolutional code and its performance in the mobile image communication system

In this paper, two novel interleaving schemes suitable for a convolutional code are given as the block interleaving scheme and bit interleaving scheme. Based on convolutional coding with Viterbi decoding, the anti-interference performance of the (2,1,3) convolutional code using these two schemes in a mobile image communication system is studied and compared with the performance using traditional periodic interleaving scheme. The simulation results show that periodic interleaving scheme is not suitable for a convolutional code. The reliability of an image transmission system in a fast fading mobile channel can be improved greatly by adopting the (2,1,3) convolutional code combined with block interleaving scheme or bit interleaving scheme as the anti-interference measure
