【摘要】：随着无线通信技术的高速发展,无线电波传播特性已成为一个热点研究课题,它关系到移动通信系统的容量确定、天线的型号选择、基站天线架设、小区蜂窝的划分等一系列技术问题。由于各种新业务的不断应用,用户数量的不断增加。为了有限频谱资源的条件下满足用户更多的通信需求,小区蜂窝的划分越来越细,频率复用率越来越高;另外信号的传播具有很强的随机性,信号能量波动大,同周围的物理环境有很大的关系,必然导致区域内的信号源相互之间的干扰趋于严重。为了达到最佳的通信质量,在移动通信的基站和系统的设计规划过程中越来越需要运用各种软件、模型进行预测仿真和分析。本文通过对典型地貌的特征及信号在该环境下传播特性的分析,建立了若干具体环境下电波传播和干扰预测模型,进行了大量的预测仿真对比,验证了预测模型的正确性;并用Delphi语言开发了用于移动通信系统规划设计的电波传播与干扰预测软件。软件的主要功能是预测基站发射的信号在用户接收点的衰减情况和移动通信基站发射的信号与其它无线电系统的干扰情况。该软件对移动通信基站的规划设计具有一定的指导作用。
[Abstract]:With the rapid development of wireless communication technology, radio wave propagation characteristics have become a hot research topic, which is related to the capacity determination of mobile communication system, the choice of antenna type, the installation of base station antenna, and so on. A series of technical problems such as cell division. As a result of the constant application of various new services, the number of users continues to increase. In order to meet more communication needs of users under the condition of limited spectrum resources, the division of cell cells becomes more and more fine, and the frequency reuse rate becomes higher and higher. In addition, the signal propagation has a strong randomness, the signal energy fluctuates greatly, and has a great relationship with the surrounding physical environment, which will inevitably lead to the interference between the signal sources in the region tends to be serious. In order to achieve the best communication quality, it is more and more necessary to use various software and models to predict and analyze the design and planning of mobile communication base stations and systems. Based on the analysis of the characteristics of typical landforms and the propagation characteristics of signals in this environment, several prediction models of radio wave propagation and interference are established in this paper, and a large number of prediction simulations are carried out to verify the correctness of the prediction model. The software of radio wave propagation and interference prediction for mobile communication system planning and design is developed with Delphi language. The main function of the software is to predict the attenuation of the signals transmitted by the base station at the user receiving point and the interference between the signals transmitted by the mobile communication base stations and other radio systems. The software can guide the planning and design of mobile communication base station.
