摘　　要：在IEEE 802.15.4协议与WLAN局域网系统共存情况下,对IEEE 802.15.4协议下射频层的抗干扰性能进行实验研究。使用TI射频芯片CC2430,根据课题目的设计节点间的无线通信程序,解决了针对研究IEEE 802.15.4通信协议抗干扰性能研究需要解决的关键技术问题:DMA控制器的数据传输方式、接收节点从寄存器读取RSSI值、发送节点发送功率循环改变、发送节点及接收节点的信道循环改变并同步。根据CC2430提供的信道质量参数对不同条件下的IEEE 802.15.4抗干扰性能进行实验测试并对实验结果进行数据分析,综合测量数据,给出多种典型情况下干扰影响的定量分析。同时,分析了影响射频层丢包率的因素及其与接收信号强度指示RSSI的相关性。Under the IEEE 802.15.4 protocol and LAN system WLAN coexistence,layer anti-jamming performance underIEEE 802.15.4 radio protocol is studied experimentally. TI radio frequency chip CC2430 is used according to the radio communica？tion program design task object nodes to solve the key problems study IEEE 802.15.4 communication protocol for the study of an？ti-jamming performance need to be addressedDMA controller for data transmission,the receiving node from the register read RSSIvalue,the sending node transmit power cycle changes,the sending node and the receiving node channel circulation changes andsynchronization. According to channel quality parameters provided by the CC2430 and experimental test results for data analysis ofIEEE 802.15.4 jamming performance under different conditions,measurement data is integrated,a variety of interference effectstypically quantitative analysis are given. At the same time,it analyzes the factors affecting the RF layer packet loss rate and the re？ceived signal strength indication RSSI correlation.
