摘要
评述了现有的电波传播预测模型,包括统计性模型(经验模型)、半经验或半确定性模型和确定性模型,简要概述了统计性模型,重点阐述基于射线追踪技术的确定性模型,最后指出建模所面临的挑战,并对其研究工作进行了展望.
This paper presents a comprehensive review of electric wave propagation prediction models for wireless communication systems including statistical models (empirical models), semi-empirical models or semi-deterministic models and deterministic models, summarizes statistical models, expatiates on the deterministic models based on ray tracing technology, points out the challenges for modeling, and presents the prospects for its research.
