In this paper, Ultra-wideband (UWB) multiple access relay channel with correlated noises at the relay and receiver is investigated. We obtain outer and inner bounds for the IEEE 802.15.3a UWB multiple access relay channel, and also, a diversity gain bound. Finally, we evaluate some results numerically and show that noise correlation coefficients play important role in determining relay position.

Previous research works have solved some of these problems, but accessibility problems related to the user interaction have not been solved yet. This work is part of a research which main goals are to provide a model-based accessible chat and a development process strategy...
