Abstract

Adaptive waveform design for dynamic spectrum access of CUWB is the keystone for realizing the Cognitive UWB system. For increasing the bandwidth efficiency while satisfying the dynamic spectrum mask, a novel waveform design method and a new modulation scheme are proposed in this paper. Utilizing the band-limited and time-limited character of bandpass Prolate Spheroidal Wave Functions (PSWF), a set of orthogonal waveforms satisfying the spectrum mask can be achieved. With the joint of PPM and PSM scheme, the data rate and the bandwidth efficiency can be fold increased.
