Improving performance of inter-vehicle communication scheme using location oriented PN code allocation technique

In this paper, improvement of the performance of the IVC system using the location oriented PN code allocation is studied. In this system, allocation of PN codes for each vehicle is easy. However interference problem occurs when multiple vehicles are locating in the area where the equivalent PN code is allocated. In order to mitigate the interference, MCS scheme is adopted under asynchronous transmission and time-slot allocation is adopted under synchronous transmission. In this paper, DS-CDMA scheme is evaluated by computer simulation. As the result, the effectiveness of the proposed IVC system is confirmed under several situations.
