Photonic generation of background-free millimeter-wave ultra-wid... ... by the Federal Communications Commission (FCC), the baseband signal (background signal) and the residual local oscillator (LO) signal should ... We discuss several schemes in this work for generating background-free MMW-UWB signals that are fully compliant ...
Background-free pulsed microwave signal generation based on spec...A novel scheme for the generation of background-free pulsed microwave signals is proposed and experimentally demonstrated based on spectral shaping, frequency-to-time mapping, and balanced photodetection. In the proposed scheme, the optical spectral ...
Efficient background removal based on two-dimensional notch filt...A background removal method based on two-dimensional notch filtering in the frequency domain for polarization interference imaging ... several parameters of PIISs, and the interferogram without a background is obtained. Both the simulated and the experimental ...
