The prediction of received power in the adjacent zone of a Dedicated Short Range Communications (DSRC) system operating inside an arched transportation tunnel is discussed. Wideband directional channel sounding was conducted inside the tunnel, and the gain, angleof-arrival and delay of each propagation path were estimated from the measured data. By simulating application antennas according to t...

In this paper, we focus on the design of similar physical layer for communication between DSRC(Dedicated short range Communication) and 4GLTE-A. In LTE-A /DSRC communication, physical layer design which involves all the processing performed on peak data rates (1Gbps for low mobility and 100Mbps for high mobility) of about 1000 times above than the 2G and 3G standards. By using these enabling te...

Vertebrate Src can be activated by specific mutations to become oncogenic. Analogous mutations in Drosophila Src64 (DSrc) induce abnormal differentiation of photoreceptor cells when expressed ectopically in the developing Drosophila adult eye. We have investigated the roles that the adapter protein, Downstream of receptor kinases (Drk), and the SH2 domain-containing tyrosine phosphatase, Corksc...

This paper presents an analysis of the technical requirements for Internet Protocol (IP) and Medium Access Control (MAC) protocol to support Dedicated Short Range Communications (DSRC) which is a critical element of the Intelligent Transportation System (ITS). This study classifies the DSRC applications into four categories: unicast vehicle-to-vehicle, unicast roadside-to-vehicle, broadcast veh...

DSRC(Dedicated Short Range Communications), which is a radio mobile communication protocol in ITS, is suited for trafic related services. Considering the current trends to introduce wireless Internet service into the mobile communication network, wireless Internet service in ITS system is valuable. An adaptive logical link control algorithm to support wireless Internet web service in DSRC based...

Dedicated short range communications (DSRC) has been regarded as one of the most promising technologies to provide a robust medium and affordable enough to be built into every vehicle. It is designed to support both road safety and commercial applications. Road safety applications will require reliable and timely wireless communications. However, as the medium access control (MAC) layer of DSRC...

A current DSRC system with 5.8 GHz for Electronic Toll Collection (ETC) is briefly discussed. The d=1 modulation code and direct demodulation system using the low IF signal are proposed for DSRC systems in the next generation. Furthermore, a simulation result of direct demodulation using Viterbi detection is presented. Key-Words: Modulation code, Viterbi detection, QPSK, Low IF, Vehicle communi...

While the importance of sulfur transfer reactions is well established for a number of biosynthetic pathways, evidence has only started to emerge that sulfurtransferases may also be major players in sulfur-based microbial energy metabolism. Among the first organisms studied in this regard is the phototrophic purple sulfur bacterium Allochromatium vinosum. During the oxidation of reduced sulfur s...
