摘要
Abstract
Under the IEEE 802.15.4 protocol and LAN system WLAN coexistence,layer anti-jamming performance under IEEE 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 addressed:DMA controller for data transmission,the receiving node from the register read RSSI value,the sending node transmit power cycle changes,the sending node and the receiving node channel circulation changes and synchronization. According to channel quality parameters provided by the CC2430 and experimental test results for data analysis of IEEE 802.15.4 jamming performance under different conditions,measurement data is integrated,a variety of interference effects typically 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.关键词
