We propose and experimentally demonstrate an upconversion, downconversion signal in radio-over-fiber (RoF) systems. Upconverter consisting of an optical interleaver and a semiconductor optical amplifier. With this upconversion technique, RF frequency ranging from 15 GHz to 42.5 GHz, shows negligible dispersion-induced carrier suppression effects, which are(More)
In many real-world scenarios especially some unconstrained environments, human faces are occluded by other objects, therefore it is difficult to obtain fully holistic face images for recognition. Most ancient face recognition algorithms have faith in face alignment and face standardization, which is highly infeasible. To address this, a effective partial(More)
