  • Asynchronous transmission for NFC card emulation mode
    Patent number: 10484215
    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.
    Type: Grant
    Filed: April 27, 2018
    Date of Patent: November 19, 2019
    Assignee: Huawei International Pte. Ltd.
    Inventors: Harya Wicaksana, Zhan Yu, Rui Yu
  • Apparatus and method for direct radio frequency (RF) sampling in near field communication (NFC) devices
    Patent number: 10187100
    Abstract: Embodiments of the invention provide a system and method for direct RF sampling a Near Field Communication (NFC) receiver at a rate higher than the carrier frequency by reducing and shifting requirements at a front end analog module to a digital module.
