Abstract: A wireless device configured to support a wireless networking protocol may utilize signal processing techniques that can mitigate the effects of jammer signals. For example, when a measured power associated with a digital sample of a received wireless signal is greater than a threshold, the wireless device may determine if the wireless signal corresponds to a wireless networking packet to be demodulated. If the wireless signal does not correspond to a wireless networking packet to be demodulated, the wireless device may adjust the threshold so that the power associated with the digital sample is less than the threshold. In other words, if the signal is a jammer signal, the wireless device may adjust its noise floor upward so that continuous reception of the same jammer signal does not trigger demodulation a second time.
