Abstract
Characteristics of the waveform for received signals are determined. Statistical and/or Cyclostationary Signal Processing algorithms are used on the characteristics to identify each signal as a communication signal having a particular protocol. Autocorrelation, spectral correlation, and power Cepstrum, among others, are used to identify the signal using periodic characteristics of the waveform in the frequency domain. Rogue devices that do not adhere to the protocol are identified and actions taken accordingly.
