Abstract
A receiver including an automatic gain control module, a digital signal processor module, and a control module. The automatic gain control module has a gain that varies from a nominal value in response to the receiver receiving an input signal. The automatic gain control module is configured to generate a first signal in response to the gain settling at a value different from the nominal value. In response to the input signal not being an interference signal, the digital signal processor module is configured to process the input signal and generate a second signal. Subsequent to the first signal being generated and prior to the second signal being generated, the control module is configured to determine whether the input signal is an interference signal based on whether the second signal is generated within a predetermined time period subsequent to the first signal being generated.
