Jammer detection

An apparatus for jammer detection, the apparatus comprising:

• means for translating a received signal from a first frequency to a second frequency using a reference signal to produce a translated received signal, the reference signal including at least one frequency having a frequency association with one or more targeted frequencies of a potential jamming signal, wherein a range of frequencies of the reference signal does not overlap a range of the one or more targeted frequencies of a potential jamming signal;
• means for converting at least a version of the translated received signal in an analog domain into a converted received signal in a digital domain;
• means for detecting that the converted received signal comprises a jamming signal based on the frequency association and using at least one threshold;
• and
• means for determining a jamming frequency of the jamming signal based on the at least one frequency of the reference signal and the frequency association.

An apparatus comprising:

• a wireless transceiver configured to be connected to one or more antennas, the wireless transceiver comprising:
• a mixer configured to be coupled between at least one antenna of the one or more antennas and a modem;
• and
• a signal generator comprising:
• a selection circuit coupled to the mixer;
• a frequency-varying local oscillator coupled to the selection circuit and configured to generate a reference signal for proximity detection at a first time and for jammer detection from another wireless transceiver at a second time;
• and
• a local oscillator coupled to the selection circuit and configured to generate a local oscillator signal for wireless communication,
• wherein the wireless transceiver is configured to adjust processing of the wireless communication based on the jammer detection by generating at least one of a plurality of transmission parameters that control one or more transmission attributes for wireless communication.
