Abstract

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.

NFC 技术支持的 5G 多频段通信天线抗干扰性能研究

为了提高 5G 多频段通信的稳定性和保真度，提出了一种基于 NFC 和 RFID 技术的抗干扰设计方法，以开发 5G 多频段通信天线的抗干扰能力。将 NFC 技术与手机技术和 RFID 识别技术相结合，构建基于 NFC 技术的 5G 多频段通信信道模型。采用独特的信号衰减技术抑制 5G 多频段通信信道之间的码间干扰。同时，提取 5G 多频段通信天线的符号特征成分，并利用 NFC 与现有非接触式智能卡技术的兼容设计来指导蓝牙匹配过程。为实现5G多频段通信天线的信道均衡设计，采用自适应采样决策均衡调整技术。根据波束成形和延迟调度方法，建立多频段通信天线的传输延迟控制。根据空间波束成形原理，实现 5G 多频段通信天线的抗干扰设计。该方法在 NFC 技术支撑的 5G 多频段通信天线抗干扰设计中具有较好的信道平衡性和较低的误码率。因此，该技术对于在移动通信设备中推广 NFC 技术具有良好的潜力和价值。最低误码率为 0.006，最短延迟为 0.251。
