Abstract: In collocated radios, interference is mitigated to permit concurrent radio operation. In response to detection of imminent transmission of interfering wireless (i.e., RF jammer) signals, gain settings of one or more stages of front-end receiver amplifiers may be quickly configured to permit concurrent frequency division operation instead of consecutive time-division operation. This expansion of concurrent operation may improve communication bandwidth and/or may produce reliable, consistent results. Gain control responsive to detection of imminent RF jamming may maintain amplification in a linear range where interference can be filtered out. Receiver gain may be shifted from a default high gain or high sensitivity setting to lower gain to maintain integrity of a signal of interest (SoI), which avoids clipping, distortion and unwanted products caused by a high power jamming signal that could otherwise make it impossible to recover the SoI. This mitigation technique supplements and/or replaces other interference mitigation techniques.
