Abstract
A system for detecting interference includes an automatic gain control (AGC) module, a peak detection module, and a control module. The AGC module selectively generates a gain-locked signal when an input signal is received. The peak detector module communicates with the AGC module and selectively generates a peak-detect signal. The control module communicates with the AGC module and the peak detector module and generates a control signal when the control module does not receive the gain-locked signal within a predetermined time after receiving the peak-detect signal.
Claims38
A system for detecting interference, comprising:
- an automatic gain control (AGC) module that selectively generates a gain-locked signal when an input signal is received;
- a peak detector module that communicates with said AGC module and that selectively generates a peak-detect signal;
- and
- a control module that communicates with said AGC module and said peak detector module and that generates a control signal when said control module does not receive said gain-locked signal within a predetermined time after receiving said peak-detect signal.
A method for detecting interference, comprising:
- selectively generating a gain-locked signal when an input signal is received;
- selectively generating a peak-detect signal;
- and
- generating a control signal when said gain-locked signal is not received within a predetermined time after receiving said peak-detect signal.
A system for detecting interference, comprising:
- automatic gain control (AGC) means for selectively generating a gain-locked signal when an input signal is received;
- peak detector means for communicating with said AGC means and for selectively generating a peak-detect signal;
- and
- control means for communicating with said AGC means and said peak detector means and for generating a control signal when said control means does not receive said gain-locked signal within a predetermined time after receiving said peak-detect signal.
