Adaptive Pulse Waveform Design Based on the Combination of Multiple PSWFs for CUWB System
一种基于多频带PSWFs组合的CUWB自适应脉冲波形设计

This paper introduces the operating fundament of Cognitive Ultra WideBand (CUWB) wireless communication system and gives a scheme of dynamically obtaining adaptive emission mask based on spectrum sensing to adapt to spectrum environment and be compatible with FCC spectral mask. Then, a method to generate adaptive CUWB shaping pulse is proposed based on weight combination of Prolate Spheroidal Wave Functions(PSWFs) matching UWB multiple sub-band spectral mask. The simulation results show that the pulse waveforms shaped by this method conform the spectral mask constraint for CUWB, adapt to dynamical variety of the spectral mask.
