Abstract
A method for inductively coupled communication is described. The method includes transmitting a carrier signal from a first device while receiving the carrier signal at a receiver of the first device. The method also includes determining a carrier level estimation using a loopback path on the receiver of the first device. The method further includes controlling a transmit power level of the first device based on a coupling strength with a second device as indicated by the carrier level estimation.
