Joint Scale-Lag Diversity in Mobile Ultra-Wideband Systems

Overview This paper considers the effect of mobility on an Ultra-WideBand (UWB) direct sequence spread spectrum communication system. Based on a uniform ring of scatterers model, the paper determines that the wideband scattering function has a "Bathtub-shaped" scale spectrum. The paper compares the performances of a scale-lag Rake and a frequency-lag Rake, each capable of leveraging the diversity that results from mobility. The scale-lag Rake receiver, whose scale- and lag-shifted basis functions are matched to the dilation delay dynamics of the wideband channel, exploits greater diversity.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
