Optimal Resource Allocation for OFDM Multiuser Channels

Overview In this paper, a unifying framework for Orthogonal Frequency Division Multiplexing (OFDM) multiuser resource allocation is presented. The isolated seeming problems of maximizing a weighted sum of rates for a given power budget P and minimizing sum power for given rate requirements R can be interpreted jointly in this framework. To this end the authors embed the problems in a higher dimensional space. Based on these results, the authors subsequently consider the combined problem of maximizing a weighted sum of rates under given rate requirements R and a fixed power budget P. This new problem is challenging, since the additional constraints do not allow to use the hitherto existing approaches.

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?
