In the data management system a significant role of the Data link layer is to convert the unreliable physical link between reader and tag into a reliable link. Therefore, the RFID system employs the Cyclic Redundancy Check (CRC) as an error detection scheme. In addition for reader to communicate with the multiple tags, an anti-collision technique is required. The technique is to coordinate the communication between the reader and the tags. The common deterministic anti-collision techniques are based on the Tree algorithm such as the Binary Tree and the Query Tree algorithms.

在接收信号的数字化、软化的实现中,数字下变频起着重要的作用。本文首先介绍了数字下 变频的组成结构,然后详细分析了数字下变频的工作原理,描述了在实现数字下变频时,设计方案所 采用的高效滤波器———CIC 滤波器和多相抽取滤波器的结构和原理。最后,用通过Simulink 对数字 下变频的性能进行了仿真。在仿真的基础上使用Insight 公司的FPGA 开发系统,用测试电路实测了 数字下变频的性(In the receiving digital signal, softening the realization, the digital down-conversion plays an important role. This article first introduced the digital down conversion of the composition, and then a detailed analysis of digital down conversion of the working principle described in the realization of digital down conversion, the design used in high-performance filters--- CIC filters and multi-phase extraction filter structure and principle. Finally, with the adoption of Simulink for digital down-conversion performance of the simulation. In the simulation based on the use of Insight s FPGA development system is measured using the test circuit of the digital down-conversion of)
