Reduced-latency stochastic decoding of LDPC codes over GF(q)
Gabi Sarkis, Warren J. Gross · 2010
Non-binary LDPC codes have excellent error-correcting performance but have not yet been widely adopted due to the high decoder implementation complexity. Stochastic decoding has been proposed as a low-complexity decoding algorithm for non-binary LDPC codes. In this paper we present a new stochastic decoding algorithm for non-binary LDPC codes using tracking forecast memories that has higher throughput and lower latency than previous stochastic decoders.
