SYSTEMS AND METHODS FOR AUTOMATIC GAIN CONTROL USING A CARRIER ESTIMATION PATH

摘要

A method is described. The method includes receiving a carrier signal by a communication device. The method also includes determining a carrier level estimation of the carrier signal using a carrier estimation path. The method further includes adjusting an attenuation and/or receiver path gain based on the carrier level estimation. The communication device may be an initiator near field communication (NFC) device.
