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 9):
The method according to  claim 1 , wherein adjusting the digital baseband sampling of the baseband sample output at the NFC card emulation mode transmitter based on the estimated CFO comprises:\n receiving an encoded bit stream from an encoder; setting Acc to zero; retrieving the estimated CFO from the memory; adding the absolute of the estimated CFO to Acc; determining if the Acc is more than a data-rate; establishing the number of samples for each encoded bit, N, which is equal to the number of samples per information bit, Bit_Len, in response to the Acc being less than the data-rate; generating the digital baseband sample for a 1 bit duration based on a value of N; determining if there are any more input sample streams; and in response to determining that there are more input sample streams, repeating the steps of adding the absolute of the estimated CFO to Acc, determining if the Acc is more than a data-rate, establishing the number of samples for each encoded bit, N, which is equal to the number of samples per information bit, Bit_Len, in response to the Acc being less than the data-rate, generating the digital baseband sample for a 1 bit duration based on a value of N, and determining if there are any more input sample streams; wherein the data-rate is equal to a sampling frequency divided by Bit_Len, and Acc is the accumulation of estimated CFO.
