Narrowband receivers are more robust to narrowband interference and to GPS signal faults, but they tend to have relatively poor multipath performance. Few current techniques are capable of mitigating ...
Most high performance GPS receivers today are wideband. In most cases, they require the wider precorrelation bandwidth for enhanced multipath mitigation capability. Wideband receivers, however, are st...
Photonic chip based tunable and reconfigurable narrowband microwave photonic filter using stimulated Brillouin scattering
Stimulated scattering modulation Nonlinear optics integrated optics Radio frequency photonics
