本文针对无线个域网 (WPAN ,WirelessPersonalAreaNetwork)工作环境复杂的干扰情况 ,提出将自适应跳频技术应用其中的方案 ,并以几个WPAN系统为例进行了定量计算 .得出了采用AFH技术后系统的误码特性 ,最后以80 2 15 1(Bluetooth)及 80 2 15 3系统为例 ,对其主要的数据速率和 16 0 0跳 /秒情况进行了数值计算 .结果表明 ,在小区域内存在多种系统工作在同一频段的情况下 ,采用AFH技术的WPAN系统抗干扰性能差不多提高了 1～ 2个数量级 .本文结论也可推广到使用高速跳频技术的其它WPAN系统 .
In this paper, a scheme of applying adaptive frequency hopping to WPAN (Wireless Personal Area Network) working environment is put forward, and several WPAN systems are taken as an example for quantitative calculation.After AFH System, and finally calculates the main data rates and 160 000 hops / s with 80 2 15 1 (Bluetooth) and 80 2 15 3 systems as examples. The results show that in the small area When multiple systems work in the same frequency band, the anti-jamming performance of the WPAN system using AFH technology is increased by almost 1-2 orders of magnitude. This conclusion can also be extended to other WPAN systems using high-speed frequency hopping technology.
