摘要

本文提出了一种基于软件定义无线电架构的多协议自动功率控制RFID读写器。考虑了不同协议的应答器功耗随时间的变化。分析了功率控制对前向数据传输的调制效应。读卡器的发射功率根据不同标准的应答器的需要实时自动调节，可以节省相当大的功率。

A novel software defined radio architecture with automatic power control for RFID readers

A novel multi-protocol RFID reader with automatic power control is proposed in this paper based on a software defined radio architecture. The transponder power consumption variation over time is considered for different protocols. The modulation effect of power control on forward data transmission is included in the analysis. The emission power of the reader is automatically tuned in real-time according to the needs of the transponders in compliance with different standards, with which a considerable amount of power can be saved.
