A Study on Good PN Code Allocation for Position Oriented PN Code Allocation Scheme in DS/CDMA IVC

IVC(inter-vehicle communication) is one of the most important research topics in ITS (intelligent transport systems). In the IVC scheme using DS/CDMA (direct sequence/code division multiple access), allocation of PN codes is a major problem to be solved. In this paper, a good PN code allocation scheme for the DS/CDMA IVC system that allocates each PN code to the position on the road is examined by computer simulation. Five kinds of the PN code allocation maps are compared under several conditions.
