摘要： A hybrid decoding algorithm for low-density parity-check codes is presented. The proposed algorithm applies different updating schemes, such as the normalized min-sum (NMS) simplification and linear approximation, to the check-node based on its degree. Meanwhile, to eliminate the dependence on the channel variance estimation, the proposed algorithm adopts a multiplicative factor to initialize the channel input and a fixed linear functions for check-node updating. From the iterative thresholds and decoding simulations, our proposed algorithm can be shown to achieve improved performance (much closer to that of the belief propagation decoding) at the expense of a slight increase in complexity to NMS algorithm.

摘要： In this letter, an ef?cient hybrid decoder for block turbo codes (BTCs) is proposed to improve the hybrid BTC decoder developed by Al-Dweik et al. A simple formula for estimating the extrinsic information is ?rst derived. Then the proposed decoder is constructed by modifying the decoder of Al-Dweik et al. using the formula. Simulation results show that the proposed decoder can substantially reduce the complexity of the decoder of Al-Dweik et al., especially for moderate and high signal-to-noise ratios, with nearly the same bit error rate performance.

摘要： In this letter, an efficient hybrid decoder for block turbo codes (BTCs) is proposed to improve the hybrid BTC decoder developed by Al-Dweik et al. A simple formula for estimating the extrinsic information is first derived. Then the proposed decoder is constructed by modifying the decoder of Al-Dweik et al. using the formula. Simulation results show that the proposed decoder can substantially reduce the complexity of the decoder of Al-Dweik et al., especially for moderate and high signal-to-noise ratios, with nearly the same bit error rate performance.
