    Abstract: A method and apparatus for demapping a double squared quadrature amplitude modulated (DSQ) symbol is disclosed. One or more first log likelihood ratios (LLRs) are determined, for a first subset of constellation points of a corresponding DSQ constellation, using an LLR approximation. One or more second LLRs are determined, for a second subset of constellation points of the DSQ constellation, using a lookup table. The DSQ symbol is then demapped to one of a plurality of constellation points of the DSQ constellation based on the first and second LLRs. For some embodiments, the first subset of constellation points may correspond with an inner region of the DSQ constellation and the second subset of constellation points may correspond with an outer region of the DSQ constellation.

    Abstract: The present technique relates to a demodulation device, a demodulation method and a program capable of realizing a demodulation process at a rate equivalent to a case where I and Q channel signals are not inverted, even when the I and Q channel signals are inverted. A frequency correction unit establishes synchronization of a frequency and clock based on a signal from a frequency synchronization unit. A channel inversion detection unit of a frame synchronization unit detects presence or absence of inversion of I and Q channel signals, and supplies, as a detection result, a channel inversion detection result to the channel inversion control unit. The channel inversion control unit switches the I and Q channel signals if the inversion has occurred, based on the channel inversion detection result. This technique can be applied to a demodulation device.

    Abstract: A post-equalization technique for recovering data bits from a coherent modulation optical signal is implemented in the digital domain by iteratively performing a decision-directed least mean square channel equalization step, a digital post filter step and a maximum likelihood sequence estimation step so that the symbol decisions of the previous iteration are fed to the decision directed least mean square channel equalization step to successively improve the symbol decisions. In an experimental setup, the iterative technique demonstrated performance improvement mitigating the bandwidth limitation as compared to a corresponding non-iterative technique.
