Abstract :
This paper presents a parallel decoding algorithm of turbo product codes (TPC) to enable simultaneous decoding of P (> 2) linear code vectors of a product code, therefore the decoding throughput is increased by P times without performance degradation. The implementation of an 8-parallel-processing decoder for TPC (64,57,4)2 with FPGA has achieved the decoding throughput of 40 Mbit/s with 4 iterative decoding at 72 MHz clock.
