Moving Towards Mmwave-Based Beyond-4G (B-4G) Technology
2013 IEEE 77th Vehicular Technology Conference (VTC Spring), 2013Availability of large untapped spectrum resources in the millimeter wave (Mmwave) band is suitable for providing a gigabit experience with true local feel using high capacity small cells. Unlike traditional cellular systems, millimeter wave transmissions do not benefit from diffraction and dispersion making it difficult for them to propagate around ...

Complete hyperbolic lattices derived from tessellations of type {4g,4g}
Journal of Algebra and Its Applications, 2016Regular tessellations of the hyperbolic plane play an important role in the design of signal constellations for digital communication systems. Self-dual tessellations of type [Formula: see text] with [Formula: see text], and [Formula: see text] have been considered where the corresponding arithmetic Fuchsian groups are derived from quaternion orders ...

IMS is a standardized service architecture defined by 3GPP, ETSI, and IETF to provide multimedia services such as videoconferencing, VoD, and voice over IP. IMS is mainly based on the SIP protocol for session initialization. The convergence to full IP has advantages but also disadvantages.

Hyperbolic Lattices with Complete Labeling Derived from {4g, 4g} Tessellations
2015Hyperbolic lattices \(\mathcal{O}\) are the basic entities used in the design of signal constellations in the hyperbolic plane. Once the identification of the arithmetic Fuchsian group in a quaternion order is made, the next step is to present the codewords of a code over a graph, or a signal constellation (quotient of an order by a proper ideal ...

Fourth-generation wireless got its official start in the United States one year ago when Clearwire Wireless made Portland, Ore., the first city to be covered by its WiMax wireless "last mile" broadband connection. Twelve months later, the shape of wireless's future is now clearly outlined: WiMax has the early lead but will eventually be overtaken by ...
