Abstract

Abstract:

Based on compressed chirp pulses and the linear superposition of these signals, a novel method to generate ultra wide band (UWB) shaping pulses was proposed. It is flexible and easy to get UWB shaping pulses, which not only can comply with the requirement of a special spectrum mask, but also can suppress the co-channel interference between UWB and the existing narrow band systems. The simulation results show that the power spectral density(PSD) distribution of the UWB shaping pulse is accorded with the federal communications commission(FCC) mask very well, and also has very high spectrum utilization ratio. It needn’t to reduce the transmitted power in the whole UWB frequency band to resolve the co-existence problem between UWB and the narrow band communication systems.

Key words: ultra wide band, shaping pulse, power spectral density, linear frequency modulation, co-channel interference
