Virtual Test Drive for Car2Car Communication and its Application on a Synchronized Switch Diversity

A reproducible semi-virtual test drive for C2C/C2X-communication is applied on a new switch diversity setup. On base of measured characteristics of a set of C2C/C2X-diversity antennas a test drive is performed in a virtual city model, creating channel data which is emulated in a hardware transmission system. By that the performance of C2C/C2X-antennas and connected RF-signal processing circuits can be analysed in a reproducible way. In a new example a switch diversity synchronization method is presented and analysed within the test drive. This setup is able to synchronize to the packets received by a commercial C2C/C2X-receiver. Based on this reproducible analysis it is shown, that the implemented switch diversity algorithm reduces packet error rates significantly compared with a single antenna transmission.
