| 摘 要： | 随着无线局域网(WLAN)的日益普及和无线个人局域网(WPAN)的飞速发展，由于共享同一频段而产生的系统间干扰不可避免。本文着重讨论基于IEEE802．1lb标准的WLAN对基于蓝芽(Bluetooth)的短距离无线通信系统的影响。在利用MATLAB和C 搭建的系统干扰模型的仿真平台上，实现了基于蓝芽物理层的自适应跳频(Adaptive Frequency Hopping-AFH)共存机制(Co—existence Mechanism)。仿真结果显示，通过简单的AFH信道选择模块，可以有效减轻WLAN对蓝芽的干扰影响。

| Abstract: | With the wide-spread popularity of WLANs and WPANs, interference problem becomes unavoidable due to different wireless systems sharing the same bandwidth of frequency. In this paper, IEEE 802.11b based WLAN and Bluetooth-based short-range radio system are discussed, focusing on the impact of interference produced by WLAN on the Bluetooth. Simulation platform based on system interference model is built with the MATLAB and C++, then AFH coexistence mechanism based on Bluetooth PHY layer is implemented. Simulation results show that applying the simple AFH Selection Box, the interference from WLAN can be reduced significantly. |
