Abstract
Vehicle-to-vehicle radio links suffer from multipath fading and interference from other vehicles. We discuss the impact of these effects on communication networks supporting an intelligent transportation system (ITS), in particular, automated vehicle control systems (AVCS's). A statistical model for this channel is considered, and the performance of the network involving many links is evaluated. We compare the performance of time division multiple access (TDMA), direct-sequence code division multiple access (DS-CDMA), and frequency hopping with TDMA in this environment. Reliability of the radio link is investigated by specifying the radio spectrum occupation for a given required reliability of the radio link.
