Title: Saeed Ghasemi and His Work in Optical Communications
Introduction
Saeed Ghasemi is an inventor based in Castelldefels, Spain. His patent work includes a method and device for carrier recovery in coherent optical communication.
Latest Patents
Ghasemi is associated with 1 patent, titled “Method and a Device for Carrier Recovery.” The invention describes a feed-forward approach for recovering a carrier in coherent optical communication. It uses a received optical signal containing pilot pulses and information-bearing signal pulses. By analyzing quadrature values from samples of a pilot pulse with a local oscillator signal, the method determines the phase difference between the received signal and the local oscillator. The carrier information in the signal pulse is then recovered using that phase difference.
Career Highlights
Ghasemi’s listed organizational affiliations include Fundació Institut de Ciències Fotòniques and Institució Catalana de Recerca i Estudis Avançats. His patent reflects work on signal processing for coherent optical communication systems.
Collaborations
His listed coworkers include Sebastián Etcheverry and Valerio Pruneri.
Conclusion
Saeed Ghasemi’s patent addresses carrier recovery in coherent optical communications, using pilot pulses and phase estimation to recover information from optical signals.
