摘要： The present invention relates to an IM-DD optical transceiver working with a double-sideband (DSB) and single-sideband (SSB) hybrid signaling. A multicarrier signal using a subcarrier interleaved configuration is transmitted from at least one transmitter towards at least one receiver through at least one optical fiber link. A respective first quality performance of each subcarrier transmitted in a DSB modulation format is compared to a respective second quality performance of each subcarrier transmitted in a SSB modulation format. The modulation format amongst DSB and SSB is respectively selected for each subcarrier as to achieve the better quality performance. A selective filling of each subcarrier can then be obtained in order to get a multicarrier signal free of CD-induced fading dips even after its transmission through the fiber link and an optical-to-electrical conversion at the receiver side.

摘要： The present invention relates to an apparatus and method for performing adaptive coding for signal transmission via a transmission system, wherein a fading characteristic of a transmission spectrum available for the signal transmission is obtained and the available transmission spectrum is divided into at least two subbands in accordance with the fading 5 characteristic. Then, a modulation format for each of the at least two subbands is selected based on the transmission characteristic of the subband. At the receiver side, signal quality of the respective different modulation formats used on the at least two subbands of the available transmission spectrum is estimated and an equalization method for the signal reception is selected based on a comparison of signal qualities estimated for the at 10 least two subbands.
