Code division multiple access for an automotive area network over power-lines

This article presents a particular application of the spread spectrum code division multiple access concept (CDMA) based on direct spread spectrum modulation (DS-SSM) for an automotive area network on power-lines. Advantages and related problems to set up the system in a car are discussed. Measurements for the evaluation of the system's performances in terms of the additive noise and the interference caused by the other users are given. Design of this communication system is made taking also into account protection against electromagnetic disturbances.< >
