This paper introduces an efficient non-binary low-density parity-check (NB-LDPC) decoder architecture, in terms of increasing decoding throughput. By taking advantages of non-binary quasi-cyclic LDPC codes, a new layered decoding algorithm and corresponding efficient hardware architecture are introduced. The proposed method can improve parallelism in decoding estimations of NB-LDPC decoder while remaining error-correcting performance. The implementations results confirmed that the proposed decoder with two threads can achieve a throughput of about 2.78 Gbps, which is around 1.63 times faster than that of the state-of-the-art decoder at almost the same hardware efficiency.
