Abstract: Systems and methods for autonomous signal modulation format identification are disclosed. In an example embodiment of the disclosed technology, a method includes mapping an input signal to Stokes space to determine whether a considered number of three-dimensional clusters value is above or below a predetermined value. The method may include selecting a modulation format from a first set of modulation formats if the considered number of three-dimensional clusters value is above the predetermined value. The method may further include applying higher-order statistics if the considered number of three-dimensional clusters value is below the predetermined value.

Abstract: Systems and methods for autonomous signal modulation format identification are disclosed. In an example embodiment of the disclosed technology, a method includes applying higher-order statistics to an input signal to identify the input signal's modulation format. The method may include applying higher-order statistics to the input signal to calculate higher-order cumulant values for the input signal as higher-order cumulants are indicative of a particular modulation format signature. The method may further include employing a decision tree to determine the modulation format of the input signal.
