Guang-yi Luo, Juan He, Sha Yang, Hongbo Hu · Proceedings of the 2018 3rd International Conference on Advances in Materials, Mechatronics and Civil Engineering (ICAMMCE 2018) · 2018
The RFID reader-writer has designed based on DSP in the paper, the reader-writer is mainly composed of reception and launch antenna module, DSP control module, receiver module, A/D conversion module, the digital baseband processing module, D/A conversion module, transmitter module, the first filter module, the second filter module and the interference signal collection module.Because of the function of DSP control module and filter module, the interference is eliminated, and the sensitivity of RFID reader is improved, which solves the problem that the interference signal of transceiver and leakage is restricted to sensitivity of read and write RFID.
