    Abstract: A method and apparatus for limiting the effect of interfering transmission on a Global Positioning System (GPS) receiver is disclosed. A first mode of operation of the GPS receiver is provided wherein the AGC of the receiver is operated in a linear state. A second mode of operation of the GPS receiver is provided wherein the AGC of the receiver is operated in a non-linear state. A first signal is provided indicating a presence of a jamming signal. In response to the first signal the GPS receiver is switched from the first mode of operation to the second mode of operation.

    Abstract: The present invention discloses a proactive gain control system for a communications receiver. The proactive gain control system includes a variable gain module for outputting an output signal in response to an input signal. A detector detects the output signal and outputs a detection signal representing a signal strength of the output signal. A traffic monitor monitors the output signal and outputs a traffic profile signal indicating that a traffic profile for the input signal will change. A gain computing module outputs a gain adjustment value in response to the detection signal and the traffic profile signal. A gain control module outputs a gain control signal to the variable gain module, which determines a gain between the input and output signals, in response to the gain adjustment value.

    Abstract: The present invention discloses a proactive gain control system (200) for a communications receiver. The proactive gain control system (200) includes a variable gain module (220) for outputting an output signal in response to an input signal. A detector (204) detects the output signal and outputs a detection signal representing a signal strength of the output signal. A traffic monitor (206) monitors the output signal and outputs a traffic profile signal indicating that a traffic profile for the input signal will change. A gain computing module (208) outputs a gain adjustment value in response to the detection signal and the traffic profile signal. A gain control module (210) outputs a gain control signal to the variable gain module (220), which determines a gain between the input and output signals, in response to the gain adjustment value.
