Signal Processing for Optical Networks

Abstract : In this report, we present a summary of research and transitions performed in the context of our study of the application of advanced signal processing concepts and techniques to various issues associated with optical fiber communication systems. We describe theoretical, simulation, and experimental studies of novel lightwave communication schemes and protocols addressed to challenges posed by extremely fast signaling rates, nonlinearities, dispersion, and attenuation. We describe analysis and design of all optical hardware for modulation, demodulation, and matched filtering. Exciting progress is reported in the areas of source and channel coding (compression and error correcting codes) for communication systems. Finally we describe interesting extensions and generalizations of matched filtering and detection algorithms and studied applications in several areas beyond communications.
