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 16):
The NFC card according to  claim 10 , wherein the sample adjustment module is configured to:\n receive an input sample stream from a subcarrier generator; set n, k and Acc to zero; retrieve the estimated CFO from the memory; add the absolute of the estimated CFO to Acc; determine if the Acc is more than the input sampling frequency of the NFC card; output the input sample stream with the following expression output[k]=input[n], in response to the Acc being determined to be less than the input sampling frequency; determine if there are any more input sample streams; and in response to determining that there are more input sample streams, increment n and k by 1 and repeat the steps of adding the absolute of the estimated CFO to Acc, determining if the Acc is more than the input sampling frequency of the NFC card, outputting the input sample stream with the following expression output[k]=input[n] in response to the Acc being determined to be less than the input sampling frequency, and determining if there are any more input sample streams; wherein n and k are variables, output[k] is an output sample number, input[n] is an input sample number, and Acc is an accumulation of estimated CFO.
