基于DSP实现RFID实时信号频谱分析

On Realizing the Real-time Signal's Spectrum Analysis in RFID Based on DSP

在RFID系统中,信号的分析与识别是极为重要的环节。基于TMS320VC5402系统,采用基二时域抽取FFT算法,对阅读器接收的信号进行实时频谱分析,从而达到对目标信息的实时采集。

In an RFID system, analyzing and identifying the signal are extremely important . In this paper, based on the hardware system which uses TMS320VC5402 and adopts radix-2 decimation-in-time FFT to analyz the signal with real time spectrum, which is received by the RFID reader, we can gather the information from the object immediately.
