Abstract

The power spectral density (PSD) of convolutionally encoded biorthogonal pulse position modulated (BPPM) time hopping (TH) ultra wideband (UWB) signals is derived. Our formulation is based on a Moore machine representation of the coding procedure and its equivalent Markov chain. The model provides for pseudo random time hopping (TH) traditionally used for multiple access purposes.
