Abstract
Two reduced-complexity (RC) LDPC decoders, which can be used in combination with large-girth LDPC codes to enable beyond 400 Gb/s serial optical transmission, are proposed. We show that optimally attenuated RC min-sum sum algorithm performs only 0.45 dB worse than conventional sum-product algorithm, while having lower storage memory requirements and much lower latency.
