Turbo product code(TPC) is a kind of forward error correction code(FEC)with excellent performance. TPC has the advantages of low decoding complexity and short decoding delay,and can achieve near-optimum performance at low signal-to-noise ratio. The soft-in soft-out(SISO)iterative decoding method for three-dimensional(3D)TPC based on Chase algorithm is intro-duced. The hardware design scheme of 3-D TPC decoder is proposed and verified on FPGA platform. The simulation results show that the decoder has high error-correcting capability and meets the requirement of mobile communication on bit error rate.
