Radio propagation predictions play an important role in the design and installation of infrastructure systems that use radio communication technologies. Although different methods are used for this purpose, ray-tracing methods such as shooting and bouncing ray have proven to be successful in terms of performance. On the other hand, unnecessary ray tracing that consumes the system resources poses a serious problem in shooting and bouncing ray simulations. In the literature, geometric or hardware-based acceleration techniques have been generally recommended for making the simulations with optimum ray tracing in indoor environments. These methods bring along dependency on environment geometry, pre-processing, cost, and coding complexities. In this study, unlike the other methods, an approach that considers the ray characteristics, not the indoor environment geometry, and performs the unnecessary ray elimination using fuzzy logic has been proposed. The results of the proposed approach have been compared with the real measurements performed in three different real indoor environments and the results of traditional shooting and bouncing ray simulations. Also, this study will present the theoretical and mathematical details of the basic principles used in shooting and bouncing ray simulations and thus serve as a reference for the researchers who want to study this field.

无线电传播预测在使用无线电通信技术的基础设施系统的设计和安装中发挥着重要作用。尽管为此目的使用了不同的方法，但已证明射击和反弹射线等光线追踪方法在性能方面是成功的。另一方面，消耗系统资源的不必要的光线追踪在射击和反弹光线模拟中造成了严重的问题。在文献中，通常推荐使用几何或基于硬件的加速技术来在室内环境中进行具有最佳光线追踪的模拟。这些方法带来了对环境几何、预处理、成本和编码复杂性的依赖。在这项研究中，与其他方法不同，一种考虑光线特性的方法，不是室内环境几何形状，并已提出使用模糊逻辑执行不必要的射线消除。已将所提出方法的结果与在三种不同的真实室内环境中进行的实际测量以及传统射击和反弹射线模拟的结果进行了比较。此外，本研究将介绍用于射击和反弹射线模拟的基本原理的理论和数学细节，从而为想要研究该领域的研究人员提供参考。
