Immunity of modulation schemes in automotive low bitrate power line communication systems

Alexnder Zeichner, Seyyed Ali Hassanpour Razavi, Stephan Frei

Abstract

In this paper, immunity of commonly employed modulation schemes for low data rate transmission over power line (PLC) are investigated. Transmitter and receiver models for Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK) and Binary Phase Shift Keying (BPSK) are implemented. Virtual automotive EMC tests, including Direct Power Injection (DPI), Bulk Current Injection (BCI) and plane wave field coupling (ALSE) were performed to investigate the immunity of the modulation schemes. Furthermore, selected pulse disturbances were tested. For method validation DPI measurements of a real PLC transceiver for automotive applications were carried out and failure behavior was compared to the virtual DPI test results. The pros and cons are discussed.
