Description: CC1100是一种低成本真正单片的UHF收发器，为低功耗无线应用而设计。电路主要设定为在315、433、868和915MHz的ISM（工业，科学和医学）和SRD（短距离设备）频率波段，也可以容易地设置为300-348 MHz、400-464 MHz和800-928 MHz的其他频率。
RF收发器集成了一个高度可配置的调制解调器。这个调制解调器支持不同的调制格式，其数据传输率可达500kbps。通过开启集成在调制解调器上的前向误差校正选项，能使性能得到提升。
CC1100为数据包处理、数据缓冲、突发数据传输、清晰信道评估、连接质量指示和电磁波激发提供广泛的硬件支持。-err

Description: 本文首先研究了IsO／IECl8000．6标准中A、B两类短程通讯的前向链路与返回
链路的数据编码方式，对(FMO)双相间隔编码、(PIE)脉冲间隔编码、曼切斯特码

进行了探讨，重点研究了ISo／IECl8000．6标准中采用的数据保护与校验技术，即
循环冗余校验(CRC)技术。分析了基于线性反馈移位寄存器(LFSR)实现CRC的电
路，从理论和实现两个方面对其中存在的问题提出了解决办法，设计了一种改进

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．
