Abstract :
This paper discusses the use of mobile cellular radio networks for providing vehicle location information to intelligent vehicle/highway system (IVHS) services. We review various automatic vehicle location (AVL) techniques in context to their application in a direct-sequence code-division multiple-access (DS/CDMA) system, in particular, the EIA/TIA/IS-95 standard proposed by Qualcomm Inc. A new matched filter location technique which is suited to the CDMA environment is discussed along with simulated error statistics and recommendations for improvement. We also consider network loading effects in terms of Signaling System 7 (SS7)
