Abstract:
A method of wireless communication includes transmitting frames from a transponder to a reader and synchronizing between a reader carrier frequency and an active load modulation (ALM) carrier frequency within each transmitted frame. Each transmitted frame includes ALM carrier bursts generated from subcarrier modulation by binary phase shift keying (BPSK) data encoding and producing signal oscillations at a transponder antenna after each ALM carrier burst generation, The synchronizing occurs at each phase change of the data encoding when no burst is generated during a half period of the subcarrier preceding the phase change and a half period of the subcarrier following this phase change. The transponder antenna has a moderate quality factor sufficient to naturally damp the signal oscillations so that the synchronizing is performed without performing any controlled signal oscillations damping.

Claim (Index 1):
A method, comprising:\n generating a data modulating signal comprising a first plurality of subcarrier periods and a second plurality of subcarrier periods in sequence to the first plurality of subcarrier periods, the first plurality of subcarrier periods being indicative of a first binary value, the second plurality of subcarrier periods being indicative of a second binary value different from the first binary value, the first plurality of subcarrier periods ending at an instant of time and the second plurality of subcarrier periods beginning at the instant of time; generating active load modulation (ALM) carrier bursts during active durations of the first plurality of subcarrier periods and during active durations of the second plurality of subcarrier periods, each ALM carrier burst having an ALM carrier frequency, wherein consecutive ALM carrier bursts are separated by inactive durations, wherein generation of the ALM carrier bursts produces signal oscillations at a transponder antenna after generation of each ALM carrier burst, and wherein a half period of the subcarrier period preceding the instant of time and the half period of the subcarrier period following the instant of time are inactive durations; and synchronizing between a reader carrier frequency and the ALM carrier frequency, wherein the synchronizing commences at the instant of time, and wherein the transponder antenna has a moderate quality factor sufficient to naturally damp the signal oscillations so that the synchronizing is performed without performing any controlled signal oscillations damping.
