Practical estimation and visualization of V2V propagation at 700 MHz band using FDTD method

Abstract

Herein, we present an effective analysis using the finite-difference time-domain (FDTD) method for vehicle-to-vehicle (V2V) radio propagation in the 700 MHz band at urban intersections. By combining the FDTD (2,4) method with multi-core processors, a high-precision computation and visualization analysis of the propagation phenomena is realized using practical computation resources for V2V communication systems in a large and complex propagation environment. We demonstrate that the causal relationship between the radio propagation process and reception characteristics can be analyzed both quantitatively and qualitatively.
