摘要
The recently proposed single block-row quasi-cyclic low-density parity-check (QC-LDPC) codes are favorable for high-speed applications. However, conventional decoder design methods are not suitable for this kind of codes. To tackle this issue, this paper aims at designing efficient column-layered single block-row QC-LDPC decoder architecture without affecting the decoding performance. Moreover, the simplified version which only requires single minimum value is also proposed for further hardware reduction. Results show that, for the rate-0.9006 (1640, 1477) single block-row QC-LDPC code, the proposed two designs achieves significant advantages in both hardware and latency over their row-layered counterpart.
