Poster: Symbol detection with OR rule for CAN FD

Controller area network (CAN) is a communication standard for in-vehicle networks and is widely employed by a number of vehicle lines. Recently, it is required for CAN to enhance bit rate because in-vehicle devices are becoming high quality and their number is increasing. CAN with flexible data-rate (CAN FD) has been recently developed to enhance the throughput in in-vehicle networks. However, higher bit rate in the data phase of CAN FD will cause severe inter-symbol interference (ISI) due to ringing, and the communication may be disabled. In this paper, symbol detection with OR rule is proposed to improve the bit reliability. The simulation results show that the proposed symbol detection attains higher bit rate than the conventional one for test networks.
