Path Loss Prediction Model Development in a Mountainous Forest Environment
IEEE Open Journal of the Communications Society, 2021 We consider a method for developing a radio-wave propagation prediction model in a mountainous forested area. A new path loss development approach uses a free-space path loss (FSPL) model and an empirical path loss model.

Practical Simplified Indoor Multiwall Path-Loss Model [PDF]
2020 20th International Conference on Control, Automation and Systems (ICCAS), 2020 Over the past few decades, attempts had been made to build a suitable channel prediction model to optimize radio transmission systems. It is particularly essential to predict the path loss due to the blockage of the signal, in indoor radio system applications.

Path Loss Modeling for Vehicle-to-Vehicle Communications [PDF]
IEEE Transactions on Vehicular Technology, 2011 Vehicle-to-vehicle (V2V) communications have received increasing attention lately, but there is a lack of reported results regarding important quantities such as path loss. This paper presents parameterized path loss models for V2V communications based on extensive sets of measurement data collected mainly under line-of-sight conditions in four ...
