V2X communications plays a significant role in increasing traffic safety and\nefficiency by enabling vehicles to exchange their status information with other\nvehicles and traffic entities in their proximity. In this regard, two\ntechnologies emerged as the main contenders for enabling V2X communications\nwhich have stringent requirements in terms of latency and reliability due to\ntheir apparent safety criticality. The first one is the DSRC standard (referred\nto as ITS-G5 in Europe) that is well researched since 20 years and has attained\nenough technical maturity for current deployment. The second one is the\nrelatively new CV2X standard that is nevertheless, based on the 3GPP standard\nfamily that have successful deployments in almost every corner of the globe. In\nthis work, we compare the link level performance of the PHY protocols for both\nthe technologies for different vehicular fading channel models. To this end, we\nconstruct and simulate the PHY pipelines and show the performance results by\nmeans of BLER versus SNR graphs. Our investigations show that CV2X performs\nbetter than ITS-G5 for almost all the considered channel models due to better\nchannel coding and estimation schemes.\n
