| Abstract(in English) | Control signal networks in vehicles using dedicated cables such as twisted wires or fiber optics cables have been built for communicating between electronic control units (ECUs). However, there are problems such as the increase of the weight of the cable harness and the difficulty to insure the reliability of the complex network architectures. Therefore, communication systems using in-vehicle power lines have been investigated. In this manuscript, we propose an impulse detection method by using two-state hidden Markovian-Gaussian noise model for the noise over in-vehicle power line. The proposed method is based on the maximum a posteriori (MAP) estimation and employs the Baum-Welch algorithm and the moment method for estimating the model parameters. We apply the proposed method to the noise generated from the model and the observed noise over in-vehicle power line and investigate the accuracy of the proposed method. |
