description: The given work is devoted to evaluating the performance of dedicated short-range communications over millimeter frequency bands. In this dissertation, the ray-launching simulator is employed to obtain such channel characteristics as path loss, root means square delay, and angular spread. In addition, an algorithm of accounting for an antenna directionality based on the vehicular network formation is proposed. Further, imitation modeling of wireless communication standard 802.11p is performed with the obtained channel parameters. In order to improve the noise immunity of the considered system, different equalization techniques are acknowledged. The results presented in this work allow to gain an understanding of millimeter-wave spectrum applicability in the context of dedicated short-range communications. The comparison of the parameters with the ones, which are reported in the literature for 5.9 GHz demonstrates the largest diversity between the path loss exponents in the non-line-of-sight condition. The difference between the root means square delay spread achieves from 10 to 40 ns with different vehicular density. Accounting for the antenna directionality reveals the inapplicability of the classical path loss approximations with the sidelobes isolation level of 30 dB. Noise immunity estimation points to the effectiveness of 802.11p transmission at 28 GHz.
