Abstract

A novel ultra-wideband (UWB) pulses design algorithm based on modified Hermite polynomials is presented in this paper. Secondary Schmidt orthogonalization method and combination algorithm are proposed to generate a class of orthogonal UWB pulses which can be used in multiple access schemes and suppress the interference between multi-users. The constructed pulse series can not only comply with the power spectral emission mask of federal communications commission (FCC), but also optimally utilize the bandwidth and power allowed. Moreover, the flexibility of combination algorithm permits simple modifications to generate new set of pulses which can accommodate other circumstances.
