Research on Extracting Cyclostionary Statistics of Amplitude-modulated Signals Based on Cumulant

摘要

Regarding the cyclostationary of of amplitude-modulated signals, a method for extracting cyclostionary statistics of amplitude-modulated signals based on Cumulant is proposed. An index, energy ratio coefficient is defined to assess signals modulated degree. Theoretical data and Simulation data are analyzed, and it is found that the energy ratio coefficient increases with the increasing modulated degree.
