Abstract

In this paper algorithm of selecting optimal sampling rate is presented from the information theory approach viewpoint. It is based on the procedure of signal samples time series entropy maximization. Efficiency increase of mutual time delay estimation algorithm is shown for multi-channel propagation of phase-shift keyed signals in the case of information-optimal sampling step.
