Abstract

The paper proposes a new method of the turbo decoding algorithm with a low error floor based on source information redundancy. The method uses the information after frame synchronization and turbo decoding to make statistics of the occurrence probability of information symbols, which is used as the extrinsic information of the input component decoder. Simulation results show that the proposed method can further reduce the bit error rate compared with the traditional turbo decoding method, decrease the threshold value of error floor effectively and improve the decoding performance without increasing the consumption of additional hardware resources and computational complexity.
