Abstract: A Kramers-Kronig receiver that may include a reception path; wherein the reception path may include a photodiode that is configured to receive a received signal and output a photocurrent that represents the received signal; wherein the received signal comprises a continuous wave (CW) signal and a modulated signal; wherein a frequency gap between the CW signal and the modulated signal is smaller than a bandwidth of the modulated signal; an analog to digital converter that is configured to generate a digital representation of the photocurrent; and a digital processor that is configured to process the digital representation of the photocurrent to provide a reconstructed modulated signal, wherein the processing is based on a Kramers-Kronig relationship related to the received signal.

Abstract: A method that may include receiving a block of signals from a certain wavelength division multiplex (WDM) channel out of a set of WDM channels; analyzing at least a first sub-block of signals of the block of signals to provide analysis results indicative of interferences that affect the first sub-block of signals and result from transmissions over other WDM channels of the set of WDM channels; and mitigating interferences that affect the block of signals in response to the analysis results.
