A new roadside information system based on a frequency-hopping (FH) code division multiple access (CDMA) system
S.V. Marić · 2002
We address the possibility of applying a new type of a frequency hopping system in order to deliver information from roadside beacons to passing vehicles. The system is based on being able to divide the FH addresses into two parts and use one of them as a group address and the other as individual address. Families of FH codes suitable for this application are given. The information class CDMA in the context of FH is also explained and some examples given.
