System and Method for Classifying Signal Modulations

摘要

A method for pre-processing a signal prior to classification, where the signal includes non-contiguous segments; the method includes applying a coarse carrier frequency offset correction, applying a phase correction, applying a residual course frequency offset correction, and outputting a simulated continuous signal consisting of recorded continuous signal segments and modeled non-contiguous segments. A system for implementing the method is also disclosed.

1. A signal classifying unit comprising
a processor; a signal receiver for receiving and recording radio-frequency signals; wherein said receiver is interruptible such that segments of the recorded radio-frequency signal are non-contiguous; a medium storing instructions executable by the processor for modeling said non-contiguous segments; wherein said instructions include instructions to:
apply a coarse carrier frequency offset correction;apply a phase correction;apply a residual course frequency offset correction; and,output a simulated continuous signal consisting of recorded continuous signal segments and modeled non-contiguous segments; a signal classifier receiving the outputted simulated continuous signal for classifying the simulated continuous signal.
