Abstract

The use of multi-antenna systems on vehicular platforms, for the implementation of ad-hoc wireless network architectures, is typically hampered by the problem of cosite interference between transceivers loading neighboring radiating elements. This paper presents a rigorous, full-wave analysis of effects pertinent to vehicular multi-antenna system performance, based on a hybrid time-domain analysis that combines electromagnetic modeling methods (such as FDTD and MRTD) with advanced SPICE-type circuit solvers. For the fast solution of such problems, MPI-based parallelization strategies are developed. Applications where the combined circuit and electromagnetic simulation of multi-antenna systems sheds light to the serious impact of mutual transceiver interference on wireless network operation are provided. In addition, the way in which a combination of the Method of Moments with the Finite Difference Time Domain can lead to the simulation of cosite interference within a forest environment is presented.
