Processing Algorithms

A communications method is presented based on the backscatter modulation of incident radio frequency signals using low-complexity tags. The incident signals arise from digital television stations used as illuminators of opportunity. A receiver detects the tag using coherent processing algorithms similar to those used in passive radar, extending the detection range over published noncoherent techniques. This method enables shared use of the UHF television band for low-data-rate applications. While analyses suggest that rates exceeding 1 kbps might be achievable at 1 km range, experimental results demonstrate the challenges in designing and implementing such a system.

Reader System

RFID is a technology that uses radio frequency signals coupled to the space (alternating magnetic or electromagnetic), to achieve the purpose of non-contact transfer of information and automatic identification. In this paper, RFID reader system is designed based on the MF RC500. Compared with the automatic identification technology such as the barcodes, magnetic cards and IC cards, The RFID reader has many outstanding advantages: firstly, it is safe and suitable for high security terminal. The second, a plurality of electronic tags can be recognized simultaneously. The third, there is no mechanical wear. The fourth, it is convenient to use with non-contact operation and without human intervention when identifying.
