Spectral efficiency analysis of digital signals for 3.1–10.6 GHz ultra-wideband radio systems

Fedor F. Dubrovka, V. A. Tretiakov

Abstract


Spectral efficiency analysis of widely used types of digital signals in the 3.1–10.6 GHz frequency band is presented. Peculiarities of energy accumulation in the specified frequency band are demonstrated for video signals and modulated signals. Optimal durations, which provide maximum value of spectral efficiency, of the considered video signals are determined. Practical recommendations on using the considered digital signals in the 3.1–10.6 GHz ultra-wideband radio systems are concluded.


Keywords
