A Vehicle-to-Vehicle Channel Model for Tactical Communication Environments

In the tactical communication environments, the characteristics of the wireless channel between mobile vehicle platforms become more complicated. The impact of the special tactical factors is not taken into account in the traditional mobile channel models. Therefore, these models are difficult to be applied directly to the design and optimization of vehicular systems in the tactical scenarios. In order to address the limitation of traditional mobile channel models, a Tactical Vehicle-to-Vehicle (T-V2V) channel model is proposed for the tactical communication environments, which considers jointly the influences of the mutual movement between two vehicle platforms, the alignment problem of directional antennas and the tactical terrain. Then, the proposed model is statistically analyzed based on the index of the Lever Crossing Rate (LCR) and the Average Duration of Fading (ADF). The simulation results show that the proposed model is more suitable for the actual situation and reflects the changing characteristics of V2V channel more accurately in the tactical environments. Finally, the relevant factors of the proposed model are analyzed and the conclusions can provide important guiding significance for the physical layer design in tactical communication environments.
