Joint Source-Channel Coding for First-Order Hidden Markov Source

In this paper, a novel Joint Source-Channel Coding scheme based on Irregular Repeat-Accumulate codec is proposed for the transmission of Hidden Markov Source in AWGN scenarios. The encoder structure of the scheme consists of two units, one for source assign and another for encode. The simulation results demonstrate that the proposed scheme have better compression performance than the traditional code model and can exploit the different transmission performance based on four different types sources.
