Description: Radio Frequency Identification (RFID) systems have recently received a lot of attention
in supply chain applications. One of the challenges facing RFID in this application
domain is the fast identification of a large number of tags that are simultaneously present
in the reader range of an RFID reader. In this thesis, different transmission control
strategies were evaluated based on the EPCglobal Class-1 Generation-2 UHF RFID
protocol. These strategies focus on incorporating the capture effect and an accurate tag
population estimate. To facilitate the evaluation, a Java-based simulator of the MAC
layer of the above protocol was implemented.

Description: 工作在UHF频段的RFID系统，具有识别距离远、数据传输快等优点，是
目前应用和研究的重点。然而，超高频射频识别(UHF RFID)系统在实际应用
环境中，会受到各种干扰的影响，使得误码率增大、识别速度变慢、识别距离减
小，难以满足物联网等应用。因此，对UHF RFID系统抗干扰策略进行研究具有
重要的理论意义和实用价值。本论文以工作在UHF频段的RFID系统为对象，
对其受到的部分干扰进行了分类，在此基础上提出了相应的抗干扰策略。-The UHF RFID system has the advantage offarther identification distance，faster
data rate etc，which make it be the current focus ofapplication and research．However,
the interference from the real application environment increases the bit error rate
(BER)，reduce the identification rate and space of the UHF RFID system，and
makes it fail tO satisfy the capability requirement of the intemet of things．So the
research on anti—interference strategy of UHF RFID system has great theoretical
significance and practical value．In this paper,we chose the UHF RFID system as
study object,and classified and analyzed the interference，based on which
corresponding anti—interference strategy was put forward．
