Dual Receiver Communication System for DSRC

Abstract

This is the first study and field test analysis for DSRC (Dedicated Short distance Radio System) Vehicle wireless communication system design with first prototype developed WAVE (Wireless Access in Vehicle Environment) system platform in which IEEE802.11p and IEEE1609 standard software have been implemented. In the field test, packet reach ability as one of parameter for system evaluation has been measured for both WAVE announce frame and IP packet data between On-Board-Unit (OBU) and Road-Side-Unit (RSU). After basic WAVE functional test, it has been considered about safety application with this new DSRC technology and it is also evaluated in the field testing for informing road singe and camera steaming information transmission to vehicle. In this field testing, it is compared between single receiver concept in IEEE802.11p and dual receiver concept in Car to Car Communication Consortium (C2C-CC). Under the current existing IEEE802.11p specification, there are two types of communication channels i.e. Control Channel (CCH) and Service Channel (SCH). Those channels are sending during each 50 msec interval. The CCH is used for emergency information transmission basically and SHC is used for non- critical information such as video transmission for customer usage. Therefore it should be considered about time critical for sending CCH information. So it has been measured timing for each CCH and SCH frame arrival from RSU to OBU in real field testing as basic WAVE system functions.
