Abstract
A method for inductively coupled communications is described. The method includes generating a retransmitted modulated signal that is stronger than a received signal from a first device. The method also includes generating a suppressed carrier signal from the retransmitted modulated signal for retransmission to the first device. The method further includes filtering a superimposed signal of the suppressed carrier signal on the received signal to attenuate modulation sidebands. The method additionally includes synchronizing to the first device based on the filtered signal.
