Multipath delay profile models for ITS wireless communications are presented. Assuming roadside-to-vehicle communications and vehicle-to-vehicle communications, propagation measurement was carried out using 700MHz spectrum and delay profile models are established based on the measured data. In the paper, the method to extract the delay profile models from the measured data is firstly presented. The...
Recent years, increasing weight and deployment cost of complicated wire harness are revealing especially in a luxury car. Therefore, it is expected that in-car network is built by wireless communication having an excellent environment-compatibility, as well as wired network. In this paper, we investigate the applicability of multiband orthogonal frequency division multiplexing ultra-wideband (MB-OFDM...
As technology scales, low power design has become a significant requirement for SOC designers. Among the existing techniques, Multiple-Supply Voltage (MSV) is a popular and effective method to reduce both dynamic and static power. Besides, level shifters consume area and delay, and should be considered during floorplanning. In this paper, we present a new floorplanning system, called MVLSAF, to solve...
