Research on anti⁃jamming transmission mechanism of NFC data based on displacement sensor

NFC数据传输受内部信号及外部环境干扰的影响,抗干扰传输机制对干扰信息的识别能力较差,导致抗干扰处理后信号依旧不稳定。为此提出基于位移传感器的NFC数据抗干扰传输机制。分析位移传感器编码机制,确定解码过程,利用数据编码实现干扰检测和干扰定位。建立RS代码,分析多项式函数的乘法计算和除法计算过程,根据数学检测模型得到传输的波形信息,实现传输机制检测。实验结果表明,基于位移传感器的NFC数据抗干扰传输机制对干扰数据的识别准确率在99.95%以上,处理后信号稳定性极高。

NFC data transmission is affected by internal signal and external environmental interference,and the anti⁃interference transmission mechanism has poor ability to identify interference information,resulting in the signal still unstable after anti⁃interference processing.Therefore,an anti⁃jamming transmission mechanism of NFC data based on displacement sensor is proposed.Analyze the coding mechanism of the displacement sensor,determine the decoding process,and use data coding to achieve interference detection and interference location.Establish the RS code,analyze the multiplication and division calculation process of the polynomial function,obtain the transmitted waveform information according to the mathematical detection model,and realize the transmission mechanism detection.The experimental results show that the NFC data anti⁃jamming transmission mechanism based on the displacement sensor has a recognition accuracy of over 99.95%for the interference data,and the signal stability after processing is extremely high.
