Abstract:
A system and method for an NFC card for use in asynchronous NFC card emulation mode transmission. The method comprises estimating carrier frequency offset between a carrier frequency of a NFC reader and a carrier frequency of the NFC card, adjusting digital baseband sampling of the baseband sample output at the NFC card emulation mode transmitter based on the estimated carrier frequency offset to obtain an adjusted baseband sample output and modulating a RF transmitter in the NFC card emulation mode transmitter based on the adjusted baseband sample output.

Claim (Index 3):
The method according to  claim 1 , wherein estimating the CFO comprises:\n obtaining an in-phase component (I) and a quadrature phase component (Q) for a plurality of samples of an input signal from an Analog-to-Digital Converter (ADC) of the NFC card; computing a phase for each sample; computing phase differences between a plurality of adjacent samples from the input signal; averaging the phase differences to obtain the estimated CFO; and storing the estimated CFO in a memory of the NFC card.
