A very challenging and up-to-date topic of vehicular communications brings about certain challenges in terms of radio access technologies, spectrum allocation, networking and automation aspects. This paper provides an insight into the relevant technologies of both the physical and medium access control layers, as well as the network layer. In particular the… (More)
This work proposes a block-recursive matching algorithm (BRMA), for displacement estimation. Simulation results show that three iterations are adequate to almost reach the asymptotic performance and the improvement of the recursive method versus the nonrecursive method varies significantly from frame to frame. A smaller block size was shown to result in… (More)
The objectives of this paper are to investigate various speech coding techniques to determine their applicability to voice conferencing, to present a new technique for summing directly from the encoded signals, and to demonstrate the audio results and effectiveness of the proposed voice summing technique.
— Wireless Internet in the in-vehicle environment is an evolving reality that reflects the gradual maturity of wireless technologies. Its complexity is reflected in the diversity of wireless technologies and dynamically changing network environments. The ability to adapt to the dynamics of such environments and to survive transient failures due to network… (More)
