Abstract: In this paper, we propose a modified phase generated carrier (PGC) demodulation scheme combining dual modulation techniques for acoustic wave detection by long-cavity Fabry–Perot sensors.
Noesis Technologies Soft Output Demapper is a structural element of any modern telecom system. The receiver extracts the phase and magnitude of the carrier signal. Subsequently a decision must ...
Abstract: The phase noise caused by various factors will lead to the distortion of phase demodulation in phase-sensitive optical time domain reflectometer. In order to suppress the phase noise, a data ...
