Abstract
Embodiments of methods and systems for operating a communications device are described. In one embodiment, a method for operating a communications device that communicates via inductive coupling involves adjusting a phase configuration of the communications device in response to at least one system or environmental parameter, modulating a carrier signal with the adjusted phase configuration using active load modulation (ALM), and transmitting the modulated carrier signal from the communications device for inductive coupling. In some embodiments, the at least one system or environmental parameter is selected from one or more of the following: a distance information, a geometric information, a system code, a technology code, a transmitter current and/or a transmitter power, a detuning condition, a quality factor and a resonant frequency of a resonant system.
