多个蓝牙匹克网共存时的同频干扰性能分析
Performance analysis of co-channel interference on multi-piconets bluetooth system
【摘要】 蓝牙匹克网之间的同频干扰是蓝牙应用面临的重要问题之一。在分析蓝牙匹克网发生同频干扰原因的基础上,通过理论分析和系统仿真,对同频干扰条件下蓝牙系统的两个重要性能参数误包率和吞吐量进行了评估,提出了增强蓝牙系统性能的方案。仿真结果显示在多个匹克网共存时,匹克网的数目对蓝牙系统的误包率和吞吐量有重要的影响,采用正交跳频序列可以有效改善蓝牙系统的性能。
【Abstract】 The co-channel interference of bluetooth multi-piconets is considered as one of an important problem in reality.Based on anal-yzing the reasons of co-channel interference,by computer-aided simulation and theoretical analysis,the packet error probability and ag-gregated throughput were evaluated which are two important system performance parameters and a treatment of enhancing system per-formance was proposed under co-channel interference.Simulation results reveals that the number of piconet would impact on packet error probability and aggregated throughput seriously and orthogonal frequency hopping can improve the system performance effectively on multi-piconets system.
【Key words】 bluetooth piconet; co-channelinterference; packeterrorprobability; aggregated throughput; orthogonal frequency hopping;
