摘要

本文首次提出了影响超高频RFID数字接收机性能的各种因素

明确了噪声和直流偏移干扰对读写器性能的影响关系.给出包含过采样滤波、直流偏移校正、相关性解码等基带数字信号处理方案

并在Altera FPGA上进行了验证.结果证明它比其他方法可以有效提高超高频RFID读写器的读取效果.

Abstract

By analysis the factors which affect of UHF RFID reader's digital receiver

make it clear between signal noise first time

DC offset and receiver performance.A novel design of Base-band digital signal process method for Zero-IF receiver is presented

such as oversample filtering

DC offset adjust and correlation decode to solve this problem.The methods are implemented on Altera's FPGA and got better performance than other methods.
