Bit Error Recording and Modelling of In-Vehicle Power Line Communication

This work extends on previous research done by using developed experimental methods and Markov modelling to create more Markov models based on further experimental data. In previous work, bit error recordings were performed over an in-vehicle DC power bus as a communication channel when the engine was off, and the key was in 'accessories' position. In this work we extend this work by performing the same bit error recording exercise with the vehicle in different states; namely with the engine off, but a cell phone charger plugged in, windscreen wipers on, as well as these conditions with the engine on. Using the Finite State Spreading Chain model developed in previous work, we create Markov models for the channel under each of these conditions.
