Abstract :
Cognitive ultra-wideband (UWB) radio is proposed to exploit the advantages and the unique features of cognitive radio to enhance the functionality of UWB wireless technology. In order to achieve the cognitive UWB radio, cognitive pulse based on modified orthogonal Hermite polynomials is proposed in this paper for producing arbitrary expected spectral notches while matching with the Federal Communication Commission (FCC) spectral mask. The spectral notches can be adjusted dynamically according the interference of environments. Simulation result showed that the cognitive pulse could reduce the effect of narrow band interference on UWB system with litter complexity
