Abstract: The present disclosure describes systems and methods for identifying a signal that is a product of two or more other signals. In an embodiment, intermodulation distortion is determined by searching a frequency band for an RF product signal and identifying the RF product signal as an intermodulation distortion signal using a cyclostationarity detection technique.

Abstract: The present disclosure describes systems and methods for identifying a signal that is a product of two or more other signals. In an embodiment, the presence of intermodulation distortion in a communication system is determined by comparing a cyclic autocorrelation function (“CAF”) of a complex envelop of signal content in a frequency bin, comparing the determined CAF with the CAF for a known signal type, and comparing a frequency of the signal content with the frequency of an RF channel in the communication system.

Abstract: The present disclosure describes systems and methods for identifying a signal that is a product of two or more other signals. In an embodiment, the presence of a particular signal is determined and identified by applying a cyclostationarity detection technique, such as comparing a cyclic autocorrelation function of a product signal with the cyclic autocorrelation function of at least one of the signals which formed the product signal.
