Proactive gain control system for communications receivers

A proactive gain control system for a communications receiver, comprising:

• a variable gain module for outputting an output signal in response to an input signal;
• a detector for detecting the output signal and outputting a detection signal representing a signal strength of the output signal;
• a traffic monitor for monitoring the output signal and outputting a traffic profile signal indicating that a traffic profile for the input signal will change;
• a gain computing module for outputting a gain adjustment value in response to the detection signal and the traffic profile signal;
• a gain control module for outputting 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;
• and
• an analog-to-digital converter for converting the output signal from an analog format into a digital format, before the output signal is detected and monitored by the detector and the traffic monitor, respectively.
