future generations of cellular communications require higher data rates and more reliable transmission link .Cooperative communications have a great significant in modern communications as they improve the information transmission between the source and the destination by using the relays. The relaying schemes are Amplify-and-Forward (AF) in which the relay sends an amplified copy of its receiv...

Mobile receivers can benefit from an increased spatial diversity through cooperation. Two relaying techniques are typically used : either Amplify and Forward (AF) or Decode and Forward (DF). This contribution presents a new technique which combines the main advantages of both AF and DF. This technique amounts to a DF scheme where all operations are performed in a soft-input soft-output fashion....

Title of Dissertation: COGNITIVE MULTIPLE ACCESS FOR COOPERATIVE COMMUNICATIONS AND NETWORKING Amr A. El-Sherif, Doctor of Philosophy, 2009 Dissertation directed by: Professor K. J. Ray Liu Department of Electrical and Computer Engineering In cooperative communications different network nodes share their antennas and resources to form a virtual antenna array and improve their performance throug...

1. Introduction The development of intelligent vehicle safety systems is rapidly moving from autonomous systems relying on vehicle's own sensors towards cooperative systems utilising communications between vehicles or between infrastructure and vehicles. The paper discusses the results of two recent European studies assessing the socio economic impacts of intelligent vehicle systems, including ...

Millimeter-Wave (mmWave) Vehicle-To-Vehicle (V2V) communications are a key enabler for connected and automated vehicles, as they support the low-latency exchange of control signals high-resolution imaging data maneuvering coordination. The employment mmWave V2V calls Beam Alignment Tracking (BAT) procedures to ensure that antenna beams properly steered during motion. conventional beam sweeping ...
