Channel simulation and synchronization for bistatic ICAS systems based on OFDM waveforms

Abstract:
Integrated communications and sensing systems in the context of automated driving promise increased road safety, especially if the systems are interconnected to form networks. This however places high demands on time and fre-quency synchronization which lie beyond radio network requirements. In this paper, a simulation of a time varying bistatic ICAS channel as well as generation and transmission of an orthogonal frequency division multiplexing frame is presented. The influence of receiver location on the synchronisation quality is analysed. It is found for the investigated scene that synchronization is especially affected if no line-of-sight connection between transmitter and receiver is available.
