The Waveform Design for Dynamic Spectrum Access of CUWB with High Bandwidth Efficiency

摘要：

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.
