Abstract
An apparatus is disclosed for adaptive jammer detection. In example aspects, the apparatus includes at least one communication processor and wireless circuitry. The at least one communication processor is configured to determine a performance indication corresponding to a received signal. The at least one communication processor is also configured to adjust a jammer detection threshold based on the performance indication to produce an adjusted jammer detection threshold. The wireless circuitry is coupled to the at least one communication processor and includes a jammer detector. The jammer detector is configured to detect a first jamming signal based on the jammer detection threshold and to detect a second jamming signal based on the adjusted jammer detection threshold.

An apparatus comprising:
- at least one communication processor configured to:
- determine a performance indication corresponding to a received signal;
- and
- adjust a jammer detection threshold based on the performance indication to produce an adjusted jammer detection threshold;
- and
- wireless circuitry coupled to the at least one communication processor, the wireless circuitry comprising a jammer detector configured to:
- detect a first jamming signal based on the jammer detection threshold;
- and
- detect a second jamming signal based on the adjusted jammer detection threshold,
- wherein:
- the at least one communication processor is configured to determine the performance indication over a first time period;
- and
- the jammer detector is configured to detect at least one jamming signal over a second time period, the second time period shorter than the first time period.
A method for adaptive jammer detection, the method comprising:
- detecting, by jammer detection circuitry, a first jamming signal based on a first jammer detection threshold;
- determining, by at least one communication processor, a performance indication corresponding to a received signal;
- adjusting, by the at least one communication processor, the first jammer detection threshold based on the performance indication to produce a second jammer detection threshold;
