摘要
RFID设计中的核心技术之一是实现对电子标签返回信号的解码,作者分析和研究了基于ISO/ICE 15693标准的RFID系统中ASK模式响应信号的软件解码方法,在基于DSP芯片设计的读写器硬件基础上,采用了"波形追踪"的算法,充分利用DSP芯片的信号处理和运算能力,以软件方式实现了对电子标签返回的ASK响应信号的解码工作。使用效果表明该算法具有解码准确率高、速度快、工作稳定等优点。
One of the core technologies in RFID design is the decoding of the response signal from tags,analyzed the software decoding of an RFID system＇s ASK mode signal which based on ISO/ICE15693 standard.In a DSP-based RFID reader system,adopted a Wave-Track algorithm which took full advantage of the signal processing ability of DSP chip and realized the decoding of tag＇s response signal with software.The result indicated that this algorithm has advantages of high veracity,high speed and work stability.
