摘　　要：针对二维TPC码提出一种新的简化迭代译码算法以及一种新的译码器迭代结构。该算法在Chase迭代软输入软输出译码的基础上,通过简化软输入信息和外信息的计算来降低译码复杂度和系统存储量。仿真结果验证了该算法的正确性和可行性。For two-dimensional TPC codes,this paper presented a new simplified iterative decoding algorithm,and obtained a new iterative decoder structure.Its essential idea was based on the iterative SISO Chase algorithm,and by simplifying the calculation of the soft input information and external information to reduce the decoding complexity and system memory.Simulation results show the correctness and feasibility of the algorithm.
