论文摘要
V2X通信通过使车辆能够与其他车辆和交通实体交换其状态信息，从而在提高交通安全和效率方面发挥着重要作用。在这方面，有两种技术成为启用V2X通信的主要竞争者，这些技术因其明显的安全性而在潜伏期和可靠性方面具有严格的要求。第一个是DSRC标准（在欧洲被称为ITS-G5），自20年以来就经过了良好的研究，并且已经达到了足够的技术成熟度以进行当前部署。第二个是相对较新的CV2X标准，它仍然是基于在全球几乎每个角落都成功部署的3GPP标准家族。在这项工作中，我们比较了PHY协议的链路级别性能，用于不同的车辆褪色频道模型的两种技术。为此，我们构建和模拟PHY管道，并通过Bler}与SNR图显示性能结果。我们的调查表明，由于更好的通道编码和估计方案，几乎所有考虑的通道模型的CV2X几乎所有考虑的通道模型的表现都好得多。
V2X communications plays a significant role in increasing traffic safety and efficiency by enabling vehicles to exchange their status information with other vehicles and traffic entities in their proximity. In this regard, two technologies emerged as the main contenders for enabling V2X communications which have stringent requirements in terms of latency and reliability due to their apparent safety criticality. The first one is the DSRC standard (referred to as ITS-G5 in Europe) that is well researched since 20 years and has attained enough technical maturity for current deployment. The second one is the relatively new CV2X standard that is nevertheless, based on the 3GPP standard family that have successful deployments in almost every corner of the globe. In this work, we compare the link level performance of the PHY protocols for both the technologies for different vehicular fading channel models. To this end, we construct and simulate the PHY pipelines and show the performance results by means of BLER} versus SNR graphs. Our investigations show that CV2X performs better than ITS-G5 for almost all the considered channel models due to better channel coding and estimation schemes.
