实时谱分析方法在射频识别技术中的应用

The application of real-time spectrum analysis in radio frequency identification technique

本文针对NCITS256(美国行业通用标准)协议提出了一种射频识别技术中检测标签应答信号的方法,这种方法也可以应用于其它协议。与传统的检测方法相比,该方法可以提高读写器的灵敏度,从而在相同的发射功率下使射频识别系统达到更远的工作距离。

A new method for detecting the RFID tag＇s back-scattered modulation signals based on NCITS256 protocol is introduced in this paper. This method can also be used in other RFID protocols. Better sensitivity is achieved by the new method than the traditional detecting method, and longer working distance is realized than the traditional system with same transmitting power.
