Abstract:
A novel tunable multiband ultra-wide band (MB-UWB) pulses generation method using synchronously-apodized polarization modulation and birefringence time delay is proposed and demonstrated in this letter. Proper apodization profile is used to get MB-UWB pulses with spectra sidelobes suppression over 20dB. Five bands of MB-UWB pulses are generated by tuning the modulation frequency and transmitted over wireless channel. The central frequencies are from 4GHz to 6GHz and bandwidths larger than 500MHz. This method can be used in multiband modulation UWB over fiber systems.
