Abstract: Systems and methods of detecting oscillation for a wireless signal amplifier are presented. The wireless signal amplifier includes an oscillation detection module configured to generate a first waveform along a frequency domain based on a first signal that has been amplified at a first gain. The oscillation detection module is configured to generate a second waveform along the frequency domain based on a second signal that has been amplified at a different, second gain. The oscillation detection module then computes a difference between the two waveforms and configures the wireless signal amplifier to modify the gain as a function of the difference.
