a summary:Wireless canal modeling plays a pivotal role in designing, analyzing and improving wireless communication systems. However, the development of effective channel modeling approach was a long -term challenge. This problem was escalated due to the deployment of the dense network, the largest aerobic prescriptions, and the width of the broader frequency range in the next generation networks. To face this challenge, we have set WRF-GS, a new frame for the modeling of the channels based on the reconstruction of the wireless radiation field (WRF) using Sling-Gussian 3D (3D-GS). WRF-GS employs 3D alternatives and nerve networks to capture interactions between the environment and radio signals, allowing effective WRF rebuilding and depicting the properties of spread. It can then be used by the WRF to synthesize the spatial spectrum to connect the comprehensive wireless channel. While WRF-GS explains a noticeable effectiveness, it faces restrictions in capturing differences in a high frequency signal resulting from multiple multiple effects. To overcome these restrictions, we suggest WRF-GS+, an improved framework that merges electromagnetic wave physics in the nerve network design. WRF-GS+ works to take advantage of the 3D Gaussians, deformed to mix both the fixed and dynamic components of the WRF, which greatly improves its ability to describe signal differences. In addition, WRF-GS+ enhances the formation process by simplifying the 3D-GS modeling process and improving mathematical efficiency. Experimental results show that both WRF-GS and WRF-GS+ are outperforming the spatial spectrum synthesis, including the beam tracking and other deep learning methods. It is worth noting that the WRF-GS+ performs the latest performance in the RSSI signal and state prediction tasks (CSI), bypassing current methods by more than 0.7 dB and 3.36 dB, respectively.
