An experimental setup for in-circuit optimization of broadband automotive power-line communications

In this paper, an experimental setup for broadband automotive power-line communications is presented. Modular prototyping equipment is used to construct both a transmitting and receiving node on the wiring harness of a motorcar. Initial characterizing measurements are used to choose typical point-to-point communication paths. Some benchmarking results at 1 Mbps (4-FSK) and 5 Mbps (2-FSK) are also presented. This experimental setup is intended to study the suitability of various modulation techniques and frequency bands. Gathered data is also intended to help trade off performance against complexity/cost.
