Interference Suppression Arbitration Control for In-vehicle Ultra Wideband Wireless Networks

This paper proposes an interference suppression arbitration control (ISAC) method for Ultra Wideband(UWB)-based vehicular networks. The method suppresses the effects of interference by a preceding frame by activating the reception state at the optimum timing before receiving the desired frame, reducing the data loss ratio. In addition, it utilizes the preamble code's reception advantage property to prioritize critical communication equipment. The experimental results show that the method reduces the data loss rate to a 10
⁻⁵
magnitude. If this UWB-based ISAC method can be put to practical use in wireless vehicle wiring harnesses, it can be expected to reduce the weight of the wiring harness by approximately 20 %.
