摘要:

最近,毫米波(mmWave)频带已经被研究为支持新兴汽车应用的预见的极端数据率需求的手段,其超出了用于车辆通信的现有技术的能力。然而,这种潜力受到严重的各向同性路径损耗和高频信道的恶劣传播的阻碍。此外,毫米波信号通常是定向的,以受益于波束成形增益,并且需要波束的频繁重新对准以保持连接。当考虑车辆到车辆(V2V)传输时,由于车辆场景的高度移动性质,这些限制特别具有挑战性,并且对适当的车辆通信设计提出了新的挑战。在本文中,我们进行了模拟,以比较IEEE 802.11p和毫米波技术的性能,以支持V2V网络,旨在提供有关这两种技术如何相互补充,以满足未来汽车服务的要求的见解。结果表明,基于毫米波的策略支持超高传输速度,IEEE 802.11p系统有能力保证可靠和鲁棒的通信。

英文摘要:

Recently, the millimeter wave (mmWave) band has been investigated as a means to support the foreseen extreme data rate demands of emerging automotive applications, which go beyond the capabilities of existing technologies for vehicular communications. However, this potential is hindered by the severe isotropic path loss and the harsh propagation of high-frequency channels. Moreover, mmWave signals are typically directional, to benefit from beamforming gain, and require frequent realignment of the beams to maintain connectivity. These limitations are particularly challenging when considering vehicle-to-vehicle (V2V) transmissions, because of the highly mobile nature of the vehicular scenarios, and pose new challenges for proper vehicular communication design. In this paper, we conduct simulations to compare the performance of IEEE 802.11p and the mmWave technology to support V2V networking, aiming at providing insights on how both technologies can complement each other to meet the requirements of future automotive services. The results show that mmWave-based strategies support ultra-high transmission speeds, and IEEE 802.11p systems have the ability to guarantee reliable and robust communications.
