The study of path loss becomes paramount for the deployment of HSR base station infrastructure. In this letter, a new empirical path loss model for Line-of-Sight (LOS) propagation is constructed. The optimization technique is utilized to validate the model which in this term the unknown parameter values of associated HSR communication system are investigated and compared using Particle Swarm Optimization (PSO), Whale Optimization (WO) and Flower Pollination Algorithm (FPA) The given curve fitting plots adhere the dynamic scenario of HSR dataset and ultimately FPA predominates other techniques in presenting the model’s accuracy.

采用优化技术的高铁通信系统视距传播新的经验路径损耗模型

路径损耗的研究对于 HSR 基站基础设施的部署至关重要。在这封信中，构建了一个新的视距 (LOS) 传播经验路径损耗模型。优化技术用于验证模型，在本术语中，使用粒子群优化 (PSO)、鲸鱼优化 (WO) 和花卉授粉算法 (FPA) 研究和比较相关 HSR 通信系统的未知参数值。给定曲线拟合绘图遵循 HSR 数据集的动态场景，最终 FPA 在展示模型的准确性方面占主导地位。
