Abstract
A communication device generates a wireless carrier signal and communicates by modulating the wireless carrier signal. A measurement circuit of the communication device measures an inductively coupled signal that is based on the transmitted wireless carrier signal and a measurement value is calculated for that signal. The measurement value is used to select a modulation procedure that is used by the communication device to encode data to be transmitted. The communication device generates and transmits a wireless data signal based on the data to be transmitted, the selected modulation procedure, and the carrier signal.
