摘　　要：为了抑制室内局域网中的干扰,提出了一种基于多项式窗函数模型的干扰自优化方案.该方案通过测量邻信道干扰系数并拟合为多项式窗函数的方式完成信道干扰建模,通过接入点(AP)和用户共同侦听网络中其他AP的方式实现干扰触发,选用加权总干扰最小算法为各个AP实现信道最优配置.仿真结果和实测结果表明,提出的方案能增加可用信道数量,减少网络干扰,提升网络平均吞吐量.In order to eliminate the interference in wireless local area network （WLAN） , an interference self-optimization scheme was proposed based on polynomial window function interference model. The dy- namic channel allocation was adopted to acquire optimum channel configuration for each access point. The channel configuration strategy was based on adjacent channel interference measurement and data fit- ting by polynomial window function while the object was minimizing the average interference. Simulation and demonstration show that the proposed scheme can effectively reduce the network interference mean- while increase the network throughput.
