Abstract:
1. A device for wirelessly receiving a data packet, the device comprising: a first amplifier configured to provide a first variable gain; a selecting module configured to a second amplifier in communication with an output of the first amplifier, wherein the second amplifier is configured to provide a second variable gain; an automatic gain control (AGC) module configured to control each of the first variable gain and the second variable gain; and an antenna selection module configured to selectively change the selection signal in response to the first variable gain or the second variable gain after a preamble of the data packet and before a payload of the data packet, and, when the selection signal is set to the first state, to maintain the selection signal in the first state in response to determinations that: the first variable gain is less than a first predetermined gain value; and the second variable gain is less than a second predetermined gain value.
