Abstract: The present invention provides a code generator (400) for generating a {N', K'} code (102) for encoding and/or decoding data transmitted in a communication channel (101) from a {N, K} code (103), wherein N and N' are code lengths, K and K' are code dimensions. The code generator (400) is configured to shorten the {N, K} code (103) to obtain an intermediate code (401), and to extend the intermediate code (401) to obtain the {N', K'} code (102). The present invention provides also a corresponding code construction method (600). Further, the present invention provides a device (100) for encoding and/or decoding data transmitted in a communication channel (101), the device (100) being configured to encode and/or decode the data based on an {N', K'} code (102) generated from the {N, K} code (103).

Abstract: The present invention provides a cross polarization modulation, XPolM, compensator (100) for an optical coherent receiver (300). The XPolM compensator includes a receiving section (101), configured to receive digital input signals (102), a tap coefficient estimation unit (103), configured to determine tap coefficients (103tc) based on sequences (102s) of samples in the digital input signals (102), and a filter section (104), configured to obtain XPolM compensated output signals (105), based on the digital input signals (102) and on the tap coefficients (103tc).
