Patent ID: 7085255

Claim:
In a system for communicating between a plurality of transmitters and a plurality of associated receivers, utilizing repetitive time frames, each time frame subdivided into a plurality of time slots, at least a first time slot allocated to a communication between a first transmitter and a first receiver, at least a second time slot allocated to a communication between a second transmitter and a second receiver, and an N th time slot allocated to a communication between an N th transmitter and an N th receiver, an automatic gain control (AGC) system comprising: means for measuring, at said first through N th receivers, a received signal strength only during said at least first time slot associated with the respective receiver/transmitter pair, in each of a plurality of successive time frames; means for utilizing said measured signal strength to set initial gain level settings of said first through N th receivers at said allocated time slot in a subsequent time frame; means for storing a plurality of said initial gain level settings of successive time frames; means for determining a trend of the stored initial gain level settings; and means for utilizing said trend to control the gain of said first through N th receivers during the corresponding time slot in the subsequent time frame.
