This paper introduces a four-dimensional (4D) geometry-based stochastic model (GBSM) for
polarized multiple-input multiple-output (MIMO) systems with moving scatterers. We propose …

Brownian motion in one or more dimensions is extensively used as a stochastic process to
model natural and engineering signals, as well as financial data. Most works dealing with …

In the last decade, the nonstationary properties of channel models have attracted more and
more attention for many scenarios, that is, vehicle‐to‐vehicle (V2V), mobile‐to‐mobile …

A fundamental drawback of synthetic mobility models is that the spatial configuration of the
path is determined by the temporal features of the mobile station (MS), such as its speed …

This paper proposes a non-stationary channel model in which real-time dynamics of the
mobile station (MS) are taken into account. We utilize Brownian motion (BM) processes to …

In the first part of our paper, we have proposed a highly flexible trajectory model based on
the primitives of Brownian fields (BFs). In this second part, we study the statistical properties …

Secret key generation from the randomness provided by random channels is currently
considered as one way to improve security in wireless communications at the physical layer …

The IEEE 802.11 p, which operates at 5.9 GHz, is a standard used for vehicle
communications. This thesis presents new measurements of the propagation channel by …
