Abstract
Systems and methods are disclosed that include measuring power within at least one part of a wireless frequency band. These systems and methods also include calculating a variance, a mean, and a mean-to-variance ratio based upon the power measured in at least one part of the wireless frequency band using a processor. In addition, these systems and methods include comparing the mean, variance, and mean-to-variance ratio to known thresholds and determining if jamming is present within the at least one part of the wireless frequency band.
Claims22
A method, comprising:
- measuring power within at least one part of a wireless frequency band;
- calculating a variance, a mean, and a mean-to-variance ratio based upon the measured power, wherein the calculation is performed through at least one processor;
- comparing the mean, variance, and mean-to-variance ratio to known thresholds;
- determining if jamming is present within the at least one part of the wireless frequency band.
A system, comprising:
- a receiver, wherein the receiver is configured to receive wireless signals in a wireless band;
- and
- a processor, wherein the processor is configured to determine if jamming is present within the wireless signals in the wireless band by comparing the mean, variance, and mean-variance ratio of the received signals to known thresholds.
A method, comprising:
- performing a full scan of a wireless band;
- measuring the power in the wireless band;
- comparing the power in the wireless band with at least one threshold;
- determining if an interference device is present in at least one part of the wireless band.
A method, comprising:
- performing at least part of a full scan of at least one part of a wireless band;
- calculating a variance, a mean, and a mean-to-variance ration based upon the at least part of the full scan of the at least one part of the wireless band of the power observed, wherein the determination is performed through at least one processor;
- comparing the mean, variance, and mean-to-variance ratio to known thresholds;
- determining if an interference device is present in at least one part of the wireless band;
- and
- creating a notification upon the determination that the interference device is present.
