Abstract
An adaptive pulse in DS-UWB systems is characterized as being able to form nulls around some frequencies as a way to suppress its interference to licensed narrow-band users. This paper proposes an orthonormal expansion method in designing adaptive pulses, using Hermite-Gaussian functions as the orthonormal basis. An algorithm is devised and a case study provided, which shows, while satisfying the stringent FCC outdoor emission mask, the adaptive pulse designed by the algorithm can form a null as deep as 100 dB. Comparison with the matured seventh Gaussian derivative proves that the pulse also has greater spectrum utilization rate
