Capacity of a Mobile Multiple-Antenna Communication Link in Rayleigh Flat Fading

by Thomas L. Marzetta, Bertrand M. Hochwald
"... We analyze a mobile wireless link comprising M transmitter and N receiver antennas operating in a Rayleigh flat-fading environment. The propagation coefficients between every pair of transmitter and receiver antennas are statistically independent and unknown; they remain constant for a coherence int ..."

Communication Links

by Loop-bandwidth Calibrator For Serial, Joon-yeong Lee, Jong-hyeok Yoon, Hyeon-min Bae
"... Abstract—This paper describes a 10-Gb/s clock-and-data recovery (CDR) with a background optimum loop-bandwidth calibrator. The proposed CDR automatically achieves the min-imum-mean-square error between jittery input data and the recovered clock signal by adjusting the bandwidth of a CDR using Kalman ..."

Requirements for Internet Hosts - Communication Layers

by R. Braden - RFC1812] [RFC2277] Baker, F., "Requirements for IP Version 4 Routers", RFC 1812 , 1989
"... This RFC is an official specification for the Internet community. It incorporates by reference, amends, corrects, and supplements the primary protocol standards documents relating to hosts. Distribution of this document is unlimited. Summary This is one RFC of a pair that defines and discusses the r ..."

the requirements for Internet host software. This RFC covers the communications protocol layers: link layer, IP layer, and transport layer; its companion RFC-1123 covers the application and support protocols.

On limits of wireless communications in a fading environment when using multiple antennas

by G. J. Foschini, M. J. Gans - Wireless Personal Communications , 1998
"... Abstract. This paper is motivated by the need for fundamental understanding of ultimate limits of bandwidth efficient delivery of higher bit-rates in digital wireless communications and to also begin to look into how these limits might be approached. We examine exploitation of multi-element array (M ..."

communication links. We explore the important case when the channel characteristic is not available at the transmitter but the receiver knows (tracks) the characteristic which is subject to Rayleigh fading. Fixing the overall transmitted power, we express the capacity offered by MEA technology and we see how

A calculus of mobile processes, I

by Robin Milner, et al. , 1992
"... We present the a-calculus, a calculus of communicating systems in which one can naturally express processes which have changing structure. Not only may the component agents of a system be arbitrarily linked, but a communication between neighbours may carry information which changes that linkage. The ..."

1Molecular Communication Link

by Nariman Farsad, Weisi Guo, Andrew Eckford
"... Abstract—This demonstration will present the world’s first macroscale molecular communication link to reliably transmit a continuous data stream. The system modulates alcohol molecules, which are then diffused via ambient and induced air currents to carry information to a receiver. The communication ..."

Epidemic Spreading in Scale-Free Networks

by Romualdo Pastor-satorras, Alessandro Vespignani , 2000
"... The Internet, as well as many other networks, has a very complex connectivity recently modeled by the class of scale-free networks. This feature, which appears to be very efficient for a communications network, favors at the same time the spreading of computer viruses. We analyze real data from c ..."

I-TCP: Indirect TCP for mobile hosts

by Ajay Bakre, B. R. Badrinath , 1995
"... Abstract — IP-based solutions to accommodate mobile hosts within existing internetworks do not address the distinctive features of wireless mobile computing. IP-based transport protocols thus suffer from poor performance when a mobile host communicates with a host on the fixed network. This is cause ..."

Taming the Underlying Challenges of Reliable Multihop Routing in Sensor Networks

by Alec Woo, Terence Tong, David Culler - In SenSys , 2003
"... The dynamic and lossy nature of wireless communication poses major challenges to reliable, self-organizing multihop networks. These non-ideal characteristics are more problematic with the primitive, low-power radio transceivers found in sensor networks, and raise new issues that routing protocols mu ..."
