SSA Realization for Spectrum Shaping and NBI Suppression in Cognitive UWB Radios
This paper investigates spectrum shaping inultrawideband (UWB) communications and introduces spectral nulls to limit interference with narrowband signals. In order to achieve the cognitive UWB radio,a design scheme for pulse waveform optimization based on Prolate Spheroidal Wave Functions (PSWF) has been investigated for producing the expected spectral notches while matching with the required spectral mask.We simulate the UWB pulse coexisting with 802.11a system without interference.The other simulation results show thatWe can adjust transmitted signals spectrum flexibility with SSA scheme,so as to minimize interference to/from coexisting systems.
