| Abstract: | 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. |
