Abstract:The photonic bandpass sampling has been proved to be potential in multi-carrier communication, frequency-agile coherent radar, compressive sensing, etc. It supports the direct down-conversion of multi-carrier signals using a low-speed analog-to-digital converter (ADC). We observed the distortion resulted from amplitude-modulation to phase-modulation (AM-PM) conversion caused by the saturated photo-detector in the photonic bandpass sampling link. The nonlinearity caused by the AM-PM conversion is theoretically … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
