Abstract: Proposed is a method of decoding a differentially encoded PSK modulated optical data signal carrying FEC encoded data values. The optical signal is corrected by an estimated phase offset. From the corrected signal, respective likelihood values for the FEC encoded data values are derived, using an estimation algorithm which accounts for a differential encoding rule used for differentially encoding the optical signal. The derived likelihood values are limited to a predetermined range of values. From the limited likelihood values, FEC decoded data values are derived, using an algorithm which accounts for a FEC encoding rule used for FEC encoding the FEC encoded data values.

Abstract: The embodiments of the invention relate to a transmitter apparatus (TA1) for conditioning a multicarrier signal (RFS). The transmitter apparatus (TA1) contains means (FE-PU) for grouping subcarriers of the multicarrier signal (RFS) into a first frequency block, which contains a first group of the subcarriers and into at least a second frequency block, which contains at least a second group of said subcarriers. The transmitter apparatus (TA1) further contains first filtering means (LPF-1) for sideband suppression outside of the first frequency block and at least second filtering means (LPF-2, LPF-M) for simultaneous and separate sideband suppression outside of the at least second frequency block. The embodiments of the invention further relate to a method for conditioning a multicarrier signal (RFS). The method contains grouping subcarriers of the multicarrier signal (RFS) into a first frequency block, which contains a first group of said subcarriers and into at least a second frequency block, which contains at least a second group of said subcarriers. The method further contains filtering the first frequency block for sideband suppression outside the first frequency block, and filtering the at least second frequency block for simultaneous and separate sideband suppression outside the at least second frequency block. The embodiments of the invention even further relate to a computer program having a program code for performing the method, when the computer program is executed on a computer or processor and to a network node, which contains the transmitter apparatus.
