This paper focuses on the joint source-channel decoding algorithm based on Non-binary LDPC code,by source estimation of HMM.Aiming at augmenting the performance,this algorithm improves the conventional decoding algorithm of Non-binary LDPC code by adding source redundancy estimated and modifying the iterative soft information in the iterative process.The result of emulation shows its superiority over conventional methods in AWGN channel.
