A passive wireless sensor signal anti-interference method based on RFID

Abstract The study proposes an anti-interference method based on Radio Frequency Identification (RFID) technology to solve the shortcomings of current wireless passive sensors on signal reception strength and anti-interference capability. The new method improves the signal recognition capability of RFID technology by introducing the blind equalization algorithm, and further enhances the security and anti-interference effect through frequency authentication technology. The results showed that the designed method significantly improved the anti-interference performance and transmission distance of the sensor signal, and had better stability and reliability than that of the traditional method. This designed method has significant practical significance in fields such as Industrial Internet of Things and smart cities. It can effectively improve the accuracy and reliability of sensor data, enhancing the efficiency and safety of the entire system, and laying a foundation for achieving more intelligent and efficient wireless communication systems and Internet of Things applications.
