A Parallel and Memory-Efficient Decoding for Spatially-Coupled LDPC Codes

In this paper, we propose a parallel and memory-efficient decoding for spatially-coupled low-density parity-check (SC LDPC) codes. The new decoding was obtained by applying parallel architecture and efficient memory management to the windowed decoding. Simulation results show that the new decoding greatly reduces decoding latency and requires less memory, and there is no performance degradation. The advantage of the proposed decoding make it appealing in practical applications, especially in low latency scenario.
