US 2022/0360284 A1 · GAIN ADJUSTMENT CIRCUIT

Abstract

A gain adjustment circuit is coupled with a transmitting device and a receiving device that are in proximity to each other. The gain adjustment circuit receives a baseband signal that is generated based on gain signals and a power associated with a reception of a data packet by the receiving device. The gain adjustment circuit further receives previous transmission information of the transmitting device. The gain adjustment circuit predicts a time of transmission of a control packet from the transmitting device and determines whether the time of transmission overlaps with a time period of reception of the data packet by the receiving device. The gain adjustment circuit further generates and provides gain signals to the receiving device such that a signal interference during the transmission of the control packet and the reception of the data packet is mitigated.
