摘要:

目前在最先进的商用飞机上,基于IEEE 802.11b/g协议的航站楼无线局域网系统为停机位处高速无线数据传输提供了一个可行的解决方案。然而,IEEE 802.11b/g协议并不被设计具有抗干扰性能,当前停机位无线通信(指airport gate link)系统受到机场强干扰影响只能提供较低的无线传输速率。提供了一个基于IEEE 802.11g协议的自适应波束成形技术来提高当前航站楼无线局域网系统的性能。仿真结果显示所提出的方法可以有效抑制干扰并有效改善系统性能。

Abstract:

On the current most advanced commercial airplanes, IEEE 802.11b/g based system-terminal wireless LAN(TWLN)-is a wireless solution that is able to support the high speed wireless transmission for gate link. However, IEEE 802.11b/g has no resistibility against interference; due to the strong co-channel interference at the airport, the current gate link system provides a very low data rate. An IEEE 802.11g based adaptive beamforming method was provided that improved the performance of the current TWLN system. The simulation shows the proposed method is able to reject interference and significantly improve the system performance.

Key words: adaptive beamforming, interference, IEEE 802.11g, terminal wireless LAN network, airport gate link
