Abstract

This paper analyzes the possibility of increasing the spectral efficiency of phase radio-technical data transmission systems that operate under conditions of mutual interference of symbols when “transparency windows” are used. The conditions for emergency of “transparency windows” are defined, recommendations for their application with the purpose of increasing the spectral efficiency of communication systems being considered are presented. Changes in time characteristics of “transparency windows” are analyzed (their lengths over the range of channel symbol time duration) depending on the frequency detuning.

Keywords
