A parallel decoder for low latency decoding of turbo product codes

There has been intensive focus on turbo product codes (TPCs) which have low decoding complexity and achieve near-optimum performances at low signal-to-noise ratios. Different than the original TPC decoder, which performs row and column decoding in a serial fashion, we propose a parallel decoder structure. Simulation results show that with this approach, decoding latency of TPCs can be halved while maintaining virtually the same performance level.
