Research on high-speed NFC transmission based on high-efficiency EBPSK modulation

The Near Field Communication (NFC) has become one of most competitive techniques in the field of short distance wireless communication. The existed protocol does not clearly stipulate modulation mode in the high rate. Many kinds of modulation methods are used in the high rate, in which multi-ary modulation can satisfy the demand of high rate, but the high system complexity and the poor BER performance are still not entirely satisfied. Extended Binary Phase Shift Keying (EBPSK) modulation can achieve high-speed transmission with low power consumption in ultra narrow bandwidth, and the implement schemes are very simple and flexible, which are easy to integrate in the mobile phone, so high-speed NFC transmission based on EBPSK modulation would be implemented perfectly. First, EBPSK modulation and demodulation scheme are introduced. Then, the advantages of NFC-EBPSK system are presented. Finally, the simulation results are given, which will lay the foundation for the good research of high-speed NFC communication.
