A method to numerically generate orthogonal ultra wide band(UWB) shaping pulse series was proposed based on wavelet and Hermitian matrix eigenvectors.In order to construct the Hermitian matrix,an appropriate pulse in less than 1?ns duration time was generated firstly based on wavelet.Then,the orthogonal pulse series were produced through Gram-Schmidt process using the Hermitian eigenvectors given by Hermitian matrix.The simulation results show that the power spectral density(PSD) distribution of the short t...
