Abstract
Disclosed herein is a design, simulation, and hardware build
of a photonic compressed sensing Nyquist folding receiver
that is able to directly undersample wideband RF signals and
detect the original Nyquist zone and frequency information.
According to an exemplary embodiment, this is achieved by
generating a frequency modulated optical impulse train for
directly undersampling the RF environment at the antenna.
The impulse train undersamples the signals using an optical
modulator configuration at 1550 nm and collects the
detected samples in a low pass interpolation filter which is
subsequently processed to extract the undersampled signals.
