  • Based on GSM EFR (Enhanced Full Rate) parameter redundancy, this paper proposes a new structure of joint source-channel decoding based on iterative channel decoder and parameter estimation. Based on the analysis of GSM EFR parameter redundancy, the paper presents the reasonable redundancy allocation strategy to arrange the two kinds of redundancy between the source decoder and channel decoder. Also, according to the characteristic of different speech coefficient, different estimation criterions are presented. Simulation results show that the algorithm of this paper improves the receiver performance significantly.
