Abstract
A signal on a wireless communication system control channel can be identified as authentic or malicious by monitoring control channel signal strength changes. When a control channel signal level increases abnormally fast or too quickly, i.e., above a threshold value rate of increase, the control channel signal is identified as likely being from a malicious source, such as a jamming transmitter.
