Behavioral modeling of power line communication channels for automotive applications

The black-box modeling of a power line communication channel in a car is addressed in this paper. The proposed behavioral approach is based on the so-called multipath model representation, that describes the transmission of a signal on a possibly complex power network by means of a finite number of delayed echoes. Model parameters are estimated from the frequency-domain response of the channel via a well-defined modeling procedure. A first assessment on the inclusion in the model equation of the variability of the response of the channel is carried out. The effectiveness of the approach has been demonstrated on a set of real measurements carried out on a commercial automobile.
