US Patent 10218450 Interference mitigation in short-range wireless communication

Systems and techniques are described for mitigating interference in wireless communication devices. In various examples, a device may determine a first energy level of a first received wireless signal and may determine that the first energy level is above a first threshold. The device may attenuate the first received wireless signal by a first amount. The device may filter the first received wireless signal with a band pass filter with a first passband frequency range. The device may be effective to program the band pass filter with the first passband frequency range based on the detected first energy level exceeding the first threshold.
