Title: Sebastián Etcheverry: Inventor in Coherent Optical Communications
Introduction
Sebastián Etcheverry is an inventor associated with Castelldefels, Spain. His patent work concerns carrier recovery in coherent optical communication, a process that helps recover information carried by an optical signal.
Latest Patents
Etcheverry is associated with 1 patent: “Method and a Device for Carrier Recovery.” The invention describes a feed-forward method and device for recovering a carrier in coherent optical communication. It receives an optical signal containing pilot pulses and information-bearing signal pulses, then uses quadrature values from samples of a pilot pulse to determine the phase difference between the received signal and a local oscillator signal. The carrier information in the signal pulse is recovered based on that phase difference.
Career Highlights
