摘要
针对机动式平台用频设备部署集中、潜在干扰多等问题,提出了一种机动平台通信系统可用频率资源分析方法。从天线耦合量出发,建立了耦合量与通信质量的映射,并基于此分析机动平台通信系统的可用频率资源。最后,以通信车典型应用为例,分析了车载天线间同频和谐波干扰耦合量,评估了通信设备语音质量,提取了通信系统的可用频率资源,验证了该方法可行性。
An analysis method of usable frequency resource for communication system on mobile platform is proposed,aiming at solving the problems of potential interference of the method for mobile platform on which is deployed with numerous communication devices.On the basis of antennas coupling power,a mapping between coupling power and communication quality is built,based on which the usable frequency resource of communication system on platform is analyzed.Taking the typical using of communication vehicle for example,the coupling powers on the same frequency and harmonic component are analyzed,and the voice signal quality of communication device is evaluated.According to the analysis result,the usable frequency is finally abstracted,and the feasibility of this method is validated.
