摘要：Cognitive ultra wideband wireless communication system as a new type of intelligent communication system will be utilized with a variety of techniques, now research focuses on the generation and detection of short RF pulses. Prolate spheroidal wave function possess many desirable properties, such as high energy concentration and inherent Orthogonal properties, which is important because the regulatory rules for CUWB pluse have not been finalized. This paper describes an optimized pluse design for very high spectrum utilization, low Interference, divides the spectrum into several sub-bands which could be canceled in the interfering bands, combines sub-band pulse phase with spectrum overlap rate to improve spectrum utilization. So as to realize revising seamless transmitted waveform to adapt with the wireless environment efficiently.
