More Information
Summary:This invention relates to a method for non-linear equalization of the optical channel in the frequency domain in long range and high speed optical communication systems, which is based in an inverse Volterra series transfer in order to mitigate signal distortions in the said optical communication systems. It is characterized in that: - the phase and amplitude data are extracted from the received optical signal; - the signal components are digitized in analog-to-digital conversion devices; - the digitized signal feeds a physical unit of digital signal processing.
