abstract = "Transmitter and receiver configurations suitable for M-ary DPSK/differential QAM noncoherent optical transmission are proposed. It is shown that multilevel coding based on lowdensity parity-check codes as component codes is an efficient approach to achieve high-spectrally efficient noncoherent optical transmission. The multilevel coding scheme with 2 bits/s/Hz spectral efficiency based on block-circulant component codes provides the coding gain of 12.3 dB compared to uncoded 8-DPSK, and 8.3 dB compared to uncoded QDPSK.",
