Abstract
The present disclosure describes systems and methods for determining intermodulation distortion in a system such as, but not limited to, a communication system. In an embodiment, intermodulation distortion is determined by injecting a signal into a frequency band which interacts with a second signal, searching a second frequency band for a product signal formed from the first and second signals, applying a cyclostationarity detection technique to the product signal and identifying the product signal as an intermodulation distortion signal.
