Abstract

The cognitive ultra-wideband (UWB) adaptive pulses design method is presented based on Hermite matrix eigenvectors and polycycle signal to make the UWB system coexist with the existing narrow band systems.Simulation results show that the power spectral density (PSD) of the proposed adaptive UWB pulses meets with Federal Communications Commission (FCC) indoor and outdoor spectral mask and produces adaptive spectral notches.Finally

according to analysis and simulation of multi-user interference (MUI) suppression and narrow band interference (NBI) suppression for pulse amplitude modulation-time hopping (PAM-TH) UWB systems

the proposed adaptive UWB pulses have anti-interference ability.
