Abnormal-state-discrimination Method for In-vehicle Communication Channel with Power-over-Coax Circuit

We propose an abnormal-state-discrimination method for the in-vehicle communication channel with a power-over-coax (PoC) circuit. The proposed method uses digital data, such as equalizer parameters and error information, that can be obtained from general serializer/deserializer large-scale integrated circuits. Therefore, no additional components are required to diagnose the abnormal state of the channel. We specifically focus on detecting an anomaly of a PoC filter.
