LDPC-CODED MODULATION FOR ULTRA-HIGH-SPEED OPTICAL TRANSPORT IN THE PRESENCE OF PHASE NOISE |
摘要 |
Methods and systems for decoding a signal include compensating for impairments in a received signal using at least carrier phase estimation, where residual phase error remains after compensation; calculating symbol log-likelihood ratios (LLRs) for symbols in the compensated signal using Monte Carlo integration; demapping the symbols in the compensated signal using the symbol LLRs and extrinsic information from signal decoding to produce one or more estimated codewords; and decoding each estimated codeword with a decoder that generates a decoded codeword and extrinsic information. |
