A Semi-Deterministic Environment-Aided Evolutionary Channel Model for Vehicle-to-Vehicle Communications

IEEE Transactions on Vehicular Technology
The proliferation of vehicular networks paves the way to the future intelligent transportation system. In this paper, we propose a novel non-stationary vehicle-to-vehicle (V2V) wideband channel model with the aid of environment construction including in ...

RCS-Based 3-D Millimeter-Wave Channel Modeling Using Quasi-Deterministic Ray Tracing

IEEE Transactions on Antennas and Propagation, 2023
This article introduces a low-complexity ultrawideband quasi-deterministic ray tracing (QD-RT) method for statistical analysis of wireless channels. This model uses a statistical distribution to model the bistatic radar cross section (RCS) of irregular ...

Study of MIMO channels using a novel semi-deterministic model

2007 IEEE Antennas and Propagation Society International Symposium, 2007
Among different diversity schemes, space and angle diversities which can be considered as fundamental basis for the advent of MIMO systems, have been more heavily studied for the last two decades as hinted by the impressive body of literature devoted to them.

The use of semi-deterministic propagation models for the prediction of the short-term fading statistics in mobile channels

Gateway to 21st Century Communications Village. VTC 1999-Fall. IEEE VTS 50th Vehicular Technology Conference (Cat. No.99CH36324), 2003
In this paper, a semi-deterministic propagation model for the prediction of short-term fading statistics in urban mobile cellular systems is presented. The model is based on digital map information and is also used to predict coverage areas. The short-term fading is modelled by the Nakagami distribution, where the two parameters defining the ...

Spatially Consistent Air-to-Ground Channel Modeling and Simulation via 3D Shadow Projections

International Conference on Computing, Networking and Communications
We present an approach for spatially-consistent semi-deterministic Air-to-Ground (A2G) channel modeling in Unmanned Aerial Vehicle-assisted networks. We use efficient 3D building shadow projections to determine Line-of-Sight (LOS) regions, enabling fast ...

Incremental Wi-Fi Fingerprint Positioning based on Semi-supervised Reinforcement Learning

IEEE International Conference on Electro/Information Technology
In Wi-Fi-based fingerprint positioning systems, achieving both high precision and stability simultaneously has always been a challenge. In complex and dynamic environments, the model must update the fingerprint database in real-time to maintain its ...

Channel Modeling of Low Voltage NB-PLC Network using Statistical and Deterministic Channel Modeling Approaches

IEEE International Conference on Renewable Energy Research and Applications, 2018
The aim of this article is to compare the state of the art channel models proposed by Zimmermann and transmission line (TL) theory for narrowband power line communications (NB-PLC). The model proposed by Zimmermann is considered as statistical model that
