Abstract
An automatic gain control technique generates one or more gain control signals based on a known sequence of samples received in a preamble of a packet received over a particular communications link and generates one or more adjusted gain control signals based on a previously unknown sequence of samples received in a payload of a packet. In at least one embodiment of the gain control technique, time domain samples of the preamble of a symbol are used to generate the one or more gain control signals. In at least one embodiment of the gain control technique, frequency domain samples are used to generate the one or more adjusted gain control signals. The one or more gain control signals include digital and/or analog gain control signals that are provided to digital signal processing modules and/or analog circuits in an interface circuit, respectively, to adjust the gain applied to a received signal.
