Method and apparatus for providing jammer detection in a receiver

A device for detecting a jammer comprising:

• a wideband jammer detector configured to generate a wideband (WB) interrupt signal to indicate a presence of a far off in band jammer;
• a narrowband jammer detector configured to generate a narrowband (NB) interrupt signal to indicate a presence of a close in jammer;
• an interrupt logic module configured to generate a composite interrupt signal based on at least one of the WB interrupt signal and the NB interrupt signal;
• and
• means for detecting a concurrent operation jammer from a transmitter.

A wireless communication unit for jammer detection comprising:

• a plurality of receivers associated with at least one of a plurality of applications;
• a plurality of transmitters associated with the at least one of the plurality of applications;
• a wideband jammer detector configured to generate a wideband (WB) interrupt signal to indicate a presence of a wideband jammer;
• a narrowband jammer detector configured to generate a narrowband (NB) interrupt signal to indicate a presence of a narrowband jammer;
• an interrupt logic module configured to generate a composite interrupt signal based on at least one of the WB interrupt signal and the NB interrupt signal;
• a software-based jammer detector configured to detect a concurrent operation jammer from one of the plurality of transmitters;
• and
• a software-based module configured to send a notification of the concurrent operation jammer to at least one of the plurality of receivers.

A non-transitory computer-readable medium storing instructions that, when executed by a computer, cause the computer to:

• sample an input signal to generate a sampled input signal;
• downconvert the input signal to generate a downconverted input signal;
• sample the downconverted input signal to generate a sampled downconverted (SD) input signal;
• compare the sampled input signal to a wideband threshold THWB, and comparing the SD input signal to a narrowband threshold THNB;
• generate a wideband (WB) interrupt signal based on the comparison to the THWB, and generating a narrowband (NB) interrupt signal based on the comparison to the THNB;
• generate a composite interrupt signal based on one or more of the WB interrupt signal or the NB interrupt signal;
• and
• detect a concurrent jammer operation from a transmitter.
