Abstract
A method of controlling a parameter in the generation of a coherent optical signal, the method comprising the steps of: receiving a set of signal samples relating to detection of a coherent optical signal; transforming the set of signal samples into a set of spectrum samples in the frequency domain, the set of spectrum samples being an estimation of the spectrum of the coherent optical signal; calculating at least one feedback variable based on the spectrum samples; and adjusting the parameter based on the at least one feedback variable.

A method of controlling a parameter in the generation of a coherent optical signal, the method comprising the steps of:
- receiving a set of signal samples relating to detection of a coherent optical signal;
- transforming the set of signal samples into a set of spectrum samples in the frequency domain, the set of spectrum samples being an estimation of the spectrum of the coherent optical signal;
- calculating at least one feedback variable based on the spectrum samples;
- and adjusting the parameter based on the at least one feedback variable.
Coherent optical signal control apparatus comprising:
- signal processing apparatus arranged to receive a set of signal samples relating to detection of a coherent optical signal and arranged to transform the set of signal samples into a set of spectrum samples in the frequency domain, the set of spectrum samples being an estimation of the spectrum of the coherent optical signal;
- and a feedback controller arranged to calculate at least one feedback variable based on the spectrum samples and arranged to generate a feedback control signal configured to communicate the at least one feedback variable to be used to control a parameter in the generation of the coherent optical signal.
A nontransitory computer readable storage medium comprising instructions which, when executed on at least one processor, cause the at least one processor to carry out a method of controlling a parameter in the generation of a coherent optical signal, the method comprising the steps of:
- receiving a set of signal samples relating to detection of a coherent optical signal;
- transforming the set of signal samples into a set of spectrum samples in the frequency domain, the set of spectrum samples being an estimation of the spectrum of the coherent optical signal;
