摘要
无线网络发展迅速,Wi-Fi技术能够让设备高速无线连接到访问点,从而成为室内通信环境的主流技术。然而,由于无线用户数量大幅增加,通信环境中干扰增多,无线网络的性能并不令人满意,吞吐量也不高。对此,本研究尝试解决无线接入点和无线设备之间的干扰问题。首先研究了无线网络中干扰的种类和来源。然后在Linux系统下安装了一些测试工具来测试干扰。最后,用Matlab分析得出有关信道信息的数据,也为干扰管理的研究打下基础。
Wireless network improves rapidly and in the indoor wireless environment communications, Wi-Fi technology could help the devices to connect wirelessly to a nearby ＂access point＂ and has become a main- stream. However, because of the increasing number of usages and the interference in the communication envi- ronment, wireless networks don＇t offer a predictable performance and offer the lower throughputs. For this, we would like to solve the problem for the interference among those wireless access points and devices. So we＇ll first study some kinds and sources of interference, and then we implement some tools （software and hardware） to do the tests about the interference under Linux. At last, after the tests, we could use Matlab to analyze the received datas to get the information about CSI and it＇s the preparation for the study of the interference manage- ment.
