Dedicated Short Range Communications (DSRC) is an emerging technology that connects automobiles with each other and with roadside infrastructure. The U.S. Department of Transportation may soon mandate that cars be equipped with DSRC to enhance safety. This work finds that if they do, then DSRC networks could also be an important new way to provide Internet access in urban areas that is more cos...

Co-channel coexistence between Dedicated ShortRange Communications (DSRC) and Wi-Fi needs thorough study. The reason is that although the 5.850-5.925 GHz (5.9 GHz) band has been reserved for DSRC so far, the U.S. government is moving swiftly on opening the band to be shared with WiFi. However, most prior work lacks sufficient scientific rigor by relying on performance metrics such as packet del...

Dedicated Short-Range Communication (DSRC) is the emerging technology that will play a key role in supporting cooperative road safety systems and intelligent transportation systems. This technology is improving rapidly towards the development of prototypes and research platforms used for field experiments. There are many open questions about the DSRC for safety applications. How does this techn...

The dedicated short-range communication (DSRC) system is the evolving technique used in the field of intelligent transport system (ITS) and Electronic Toll Collection (ETC). The DSRC standards employs FM0 and Manchester encoding techniques to obtain dc-balance and enhances signal reliability. The codeword structure of FM0 and Manchester are different, thus limiting the hardware potential of exi...

This paper describes next generation vehicular network standard comparison among North America, Europe and Japan and provides harmonization proposal for Japanese DSRC (Dedicated Short Range Communication). The basic DSRC standards are in IEEE (Institute of Electrical and Electronics Engineers Inc.) and in ETSI (European Telecommunication Standard Institute). The IEEE and the ETSI have regular m...

OFDM PHY has been selected as North American DSRC standard (IEEE 802.11p). In this paper, we present a robust OFDM receiver suitable for DSRC systems. A synchronizer, a one-tap frequency domain equalizer (FDE), a pilot-based phase estimator and a Viterbi decoder mainly compose it. The equalizer uses normalized least-mean-square (NLMS) algorithm to track not only the variation of the DSRC channe...

Design and simulation of a microstrip patch antenna for 5.9 GHz dedicated short range communication system (DSRC) is presented in this paper. DSRC is a wireless communication technology which has been developed for the enhancement of safety of the transport system. It operates at 5.9 GHz band (5.85-5.925 GHz). It provides 75 MHz of bandwidth. The designed antenna shows good return loss of -17.5...

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...
