Single chip UHF RFID reader digital baseband design

The most important blocks in the digital part of a RFID reader are the MCU which controls all the system work in an efficient way and the modulator which is used to accomplish the digital signal processing. As now most commercial RFID readers are discrete component design and researching on implementation of single chip RFID reader is few, this paper point out a design that concentrates on the research of single chip RFID reader design in digital baseband part. In the new design, we make use of the open source IP core Leon3 which is developed by the Aeroflex Gaisler to control the digital modulator to finish the signal processing including CRC check, code and decode, filtering and so on. And all the implementations are described in VHDL and simulated by Modelsim. We use the Virtex-6 FPGA to prove that it can work properly at the same time.
