Abstract

This paper proposes a novel method utilizing chirp signals to substitute the traditional ultra-wideband (UWB) pulse waveform. With the application of the effective iterative method and the development of spectrum detection technology, the Conjugate Gradient (CG) algorithm and Cognitive Radio (CR) technology are employed to realize the adaptive filter and narrow-band interference (NBI) suppression. Utilizing the characteristics of the CG algorithm and its corresponding adaptive filter, we realize the NBI suppression and obtain the low cost and more practical UWB pulse design for a kind of optional proposes. Simulation results show that the CG adaptive filter can suppress the NBI effectively and outperforms the conventional method significantly.
