Path loss models based on stochastic rays [PDF]
IET Microwaves, Antennas & Propagation, 2007 In this paper, two-dimensional percolation lattices are applied to describe wireless propagation environment, and stochastic rays are employed to model the trajectories of radio waves. We first derive the probability that a stochastic ray undergoes certain number of collisions at a specific spatial location.

A Stochastic Approach for Analysis of Shadowing Effects in Urban Area
Advances in Electrical and Electronic Engineering, 2022 5G networks are started to be deployed in urban areas in the dynamic spectrum sharing mode. Therefore, the analysis of Non-Line-of-Sight (NLOS) shadowing effects behind buildings of different heights becomes particularly important.

The Distribution of Path Losses for Uniformly Distributed Nodes in a Circle [PDF]
, 2008 When simulating a wireless network, users/nodes are usually assumed to be distributed uniformly in space. Path losses between nodes in a simulated network are generally calculated by determining the distance between every pair of nodes and applying a ...

Path loss models with distance‐dependent weighted fitting and estimation of censored path loss data [PDF]
IET Microwaves, Antennas & Propagation, 2016 Path loss models are the most fundamental part of wireless propagation channel models. Path loss is typically modelled as a (single‐slope or multi‐slope) power‐law dependency on distance plus a log‐normally distributed shadowing attenuation.

Polarimetric distance-dependent models for large hall scenarios [PDF]
, 2016 A comprehensive polarimetric distance-dependent model of the power delay profile (PDP) and path gain is proposed. The model includes both specular multipath components (SMCs) and dense multipath components (DMC), the latter being modeled with an ...

Joint Channel and Antenna Modeling for Magnetic Induction Communication in Inhomogeneous Media
IEEE Open Journal of the Communications Society, 2020 Magnetic induction communication (MIC) demonstrates high penetration efficiency and low propagation loss in extreme environments. It is used in underground and underwater environments to enable critical applications that cannot be achieved by using ...
