Abstract

The paper considers composite ultra-wideband signals with amplitude code modulation and with intrablock positional pulse modulation. Investigation of the generalized indeterminacy function for these signals is implemented. Analytical expressions for the correlation matrix of simultaneously effective estimates of delay time and period of these signals are derived. Analysis of potential accuracy of these parameters’ estimates is performed for various modulation techniques. An algorithm is suggested for generation of modulating shift sequences.
