摘要： A receiving apparatus and method for processing a differential phase shift keying signal carrying a plurality of symbols are disclosed to provide for improved compensation of linear and non-linear noise in phase modulated optical transmission. The receiving apparatus comprises an input unit for receiving electrical signals derived from an optical signal and a calculation unit for calculating a current value of a decision variable. The current value is indicative of a differential phase shift in the optical signal between a currently received symbol and a previously received symbol as a function of the optical signal power of the optical signal for the currently received symbol and at least one previous value of the decision variable. The receiving apparatus also comprises a decision unit for determining the differential phase shift from the current value of the decision variable obtained from the calculation unit to obtain the currently received symbol.

According to the invention, on the reception side, bit errors in the digital reception signal including their position in the digital reception signal are detected, and from the detected position of the bit errors and from the assignment of the individual bytes of the digital reception signal to the respective sub-signals and transmission lines, which assignment is also known on the reception side, it is determined to which sub-signal the detected bit errors were assigned. From this one or more parameters are determined, which characterize the transmission quality of the transmission lines assigned to each sub-signal and/or allow inferences to be drawn regarding which error mechanisms of the transmission line in question impact its transmission quality.
