报告摘要:

With the growing need of advanced communication technologies, developing superior forward-error correction (FEC) schemes has become imperative. Low-density parity-check (LDPC) block codes have undoubtedly been one the most promising FEC classes recently due to their capability in approaching channel capacity. Quasi-cyclic LDPC (QC-LDPC) codes, having a regularized structure that reduces the encoder/decoder complexities, have further demonstrated the practical value of LDPC codes. It has also been proved that QC-LDPC codes can achieve as excellent error performance as random LDPC codes. With comparable decoder complexities, an LDPC convolutional code generally outperforms its block code counterpart in terms of bit error rate and net coding gain.

In this talk, we propose a new class of QC-LDPC codes, namely cyclically-coupled QC-LDPC (CC-QC-LDPC) codes, and their RAM-based decoder architecture. CC-QC-LDPC codes have a simple structure and are constructed by cyclically-coupling a number of QC-LDPC sub-codes. They can achieve throughput and error performance as excellent as LDPC convolutional codes, but with much lower hardware requirements. They are therefore promising candidates for future generations of communication systems such as long-haul optical communication systems.
