Abstract :
In summary we demonstrate the application of programmable microwave photonic phase filters to compensate a broadband antenna dispersion at a receiver front which enables to increase data rate by overcoming distortion due to antenna nonlinear spectral phase. We also show that dispersion-compensation combined with matched filtering arbitrary waveforms can be used in waveform detection. Our scheme is programmable and broadband and can be used to enhance the performance of ultrawideband wireless systems, in particular satellite communications and radar systems.
