Optimal Waveform Design for UWB Communication Based on Gaussian Derivatives

Ultra-wideband (UWB) radios have attracted great interest for their potential application in short-range high-data- rate wireless communications. High received signal noise ratio and compliance with the FCC spectral mask call for judicious design of UWB pulse shapers. In this paper, even and odd order derivatives of Gaussian pulse are used respectively as base waveforms to produce two synthesized pulses. Our method can realize high efficiency of spectral utilization in terms of normalized effective signal power (NESP). The waveform design problem can be converted into linear programming problem, which can be efficiently solved. The waveform based on even order derivatives is orthogonal with the one based on odd order derivatives.
