Abstract

Turbo product code (TPCs) can correct a lot of random error and burst, and it has the high coding gain, but its traditional serial decoding algorithm is complex and has large decoding latency. To solve these problems this paper presented a low complexity iterative decoding algorithm in parallel. Based on the iterative SISO algorithm, a new decoding project Parallel iterative decoding+simplified arithmetic was adopted, thereby, the decoding complexity, the amount of system memory and the decoding latency was reduced, while the decoding rate was improved. The simulation results show the correctness and feasibility of the algorithm.
