LDPC decoding algorithm using residual redundancy of HMM source
Wang Gui-gui · Computer Engineering and Applications Journal · 2007
Proposes a joint source-channel decoding based on HMM(hidden Markov) source and LDPC codes.The method uses the residual information in the HMM source to modify the soft information in the LDPC iterative decoding algorithm.The result shows it enhances the abilities of correcting errors and speeds up the convergence.In the end,it gives the simulation results on the AWGN channel.
