摘要
介绍一种基于DSP技术的数据采集读写器实现,该系统进行微弱信号检测,优化硬件接收调理电路设计,利用DSP实现时域信号取样快速识别算法,有效恢复淹没于强背景噪声中的微弱信号,实现了远距离UHF射频读写器。
An application of DSP sample and identifier in UHF RFID reader are presented. The system is detecting weak signal, and it＇s receive hardware design is also optimized. The system adopts DSP accomplishing the method of improving signal to noise rate, acquiring weak signal which shielded by vast powerful noise. It realizes a long distance UHF reader.
