Patent ID: 10476539

Abstract:
Adjusting automatic gain control of a receiver, in a short-range wireless system having a plurality of channels and a plurality of receiving antennas, includes setting initial gain to be set by receiver AGC based on signals received at a receiver reference antenna, receiving, at each of the receiving antennas, a signal on a current channel, and adjusting gain to be set by AGC for the signal to prevent saturation. Angle-of-arrival estimation may be performed following adjusting of the AGC. Adjusting AGC may include backing off the AGC, changing the reference antenna prior to deriving gain to be set by AGC, or determining gain to be set by AGC at additional receiving antennas, and for each antenna that is not the reference antenna and is not one of the additional antennas, selecting gain to be set by AGC from a closest one of the reference antenna and the additional antennas.
