Intra-vehicle digital communications: characterization and simulation of the electromagnetic environment

Most of the studies on electromagnetic noise and the potential sources of interference were conducted to protect analog communications and have now appeared to be insufficient given the widespread development of digital communications. New approaches appropriate for digital communications are currently under development. We have chosen to illustrate these recent approaches by focusing on the particular application of intra-vehicle transmission. In this article, we consider two examples of data transmission: wire transmissions over a power line network, better known as power line communication, and wireless links inside the vehicleʹs passenger cell. We focus on characterizing the electromagnetic environment but we also highlight the potential of reverberation chambers for reproducibly simulating multi-path environments. To cite this article: F.
