| Abstract: | On basis of the quadrature zero-IF method of UHF RFID reader,this paper designs and implements the receiver circuit for the reader's baseband processor,including its Circuit architecture and some key modules such as demodulator and decoder.HDL is used during the implementation and RTL simulation is taken to verify the design.The design made some progress in data-encoding of the physical layer,the type of modulation and some other key technologies,and the performance of UHF RFID reader was improved greatly. |
