摘　　要：基于屏蔽材料和滤波器等硬件的射频干扰解决方法仅能在一定程度上减弱干扰,很难完全消除干扰信号。提出一种使用软件程序主动控制干扰源工作状态的方法,使干扰信号频率发生偏移,避免对有效信号产生干扰。首先,分析元器件的干扰因素,研究干扰源工作状态与干扰信号频率的联系。然后,通过计算和实验找出调节干扰源工作状态的方法,使干扰信号频率偏移到无干扰的频段。最后,设计一套具备自适应调节功能的软件程序并运行,以笔记本电脑的显存和Wi-Fi为实验对象,实时监控和调节两者的状态。实验结果表明,此方案可以有效解决笔记本电脑主板上显存与Wi-Fi间的射频干扰问题。It is difficult to completely eliminate interference signals by using hardware-based radio frequency(RF)interference solutions such as shielding materials and filters,and the interference can only be reduced to a certain extent.This paper proposes a method of actively controlling the working state of interference source with a software program.The frequency of the interference signals is shifted to avoid the interference with the valid signals.Firstly,the interference factors of components are analyzed,and the relationship between the working state of interference source and the frequency of interference signal is studied.Then,through calculation and experiment,a method is found to adjust the working state of interference source so as to shift the frequency of interference signal to the frequency band without interference.Finally,a set of software programs with adaptive adjustment functions is designed and implemented.Video memory and Wi-Fi of laptop are used as experimental objects,and the status of the two is monitored and adjusted in real time.The experimental results show that this solution can effectively solve the RF interference problem between video memory and Wi-Fi on the laptop motherboards.
