摘要
基于声表面波的无线识别技术可以实现在高速运动状态下的精确的数据传输,它具有有线系统无法比拟的优势。主要讨论声表面波无线识别系统的结构原理,以及阅读器在信号处理中的调制解调算法,并进行了Matlab仿真。
Wireless identification （ID） and sensor systems based on surface acoustic wave （SAW）technology permit reliable and accurate data acquisition, where wired solutions cannot be applied. An overview of modern concepts for wireless SAW readout units is presented. Additionally, SAW sensor principles, ID-tag signal processing are discussed.
