Research on anti-interference performance of 5G multi band communication antenna supported by NFC technology

In order to improve the stability and fidelity of 5G multi-band communication, an anti-jamming design method based on NFC and RFID technology is proposed to develop the anti-jamming ability of 5G multi-band communication antenna. Combine NFC technology with mobile phone technology and RFID identification technology, then construct a 5G multi-band communication channel model based on NFC technology. A unique signal attenuation technique is used to suppress intercode interference between 5G multiband communication channels. At the same time, extract the symbolic feature components of 5G multi-band communication antenna, and the compatible design of NFC and existing contactless smart card technology is used to guide the Bluetooth matching process. In order to realize the channel equalization design of 5G multi-band communication antenna, adopt the adaptive sampling decision equalization adjustment technique. According to the beamforming and delay scheduling methods, establish the transmission delay control of the multi-band communication antenna. According to the spatial beamforming principle, realize the anti-interference design of the 5G multi-band communication antenna. This method has a better channel balance and a lower bit error rate in the anti-jamming design of 5G multi-band communication antenna supported by NFC technology. Therefore, this technology has good potential and value for promoting NFC technology in mobile communication equipment. The lowest bit error rate is 0.006, and the shortest delay is 0.251.
