Tuning Ray Tracing for Mm‐wave Coverage Prediction in Outdoor Urban Scenarios Open
Propagation characteristics at 26, 28, and 38 GHz (Ka band) in outdoor environments are analyzed through path loss measurements in two different urban scenarios and used to tune a ray‐tracing model, with specific focus on nonspecular scatt…

Investigating Correlation of Rough Surface Diffuse Scattering in Frequency Domain Open
This paper investigates numerically the correlation function in the frequency domain due to diffuse scattering originated from rough surfaces. The scattered fields are computed by means of physical optics methods. The irregularities of the…

Reverberant Room-to-Room Radio Channel Prediction by Using Rays and Graphs Open
This paper proposes a hybrid modeling approach for prediction of the room-to-room radio propagation channel. The model combines ray tracing with propagation graph. The propagation graph vertices are obtained at each room by ray tracing wit…

A Hybrid Ray and Graph Model for Simulating Vehicle-to-Vehicle Channels in Tunnels Open
Wave propagation in tunnels for vehicle-to-vehicle (V2V) communications scenarios is characterized by multiple diffuse reflections on tunnel surfaces as well as specular reflections on other objects inside the tunnel, leading to a nonstati…
