Achievable Information Rates and the Coding-Spreading Tradeoff in Finite-Sized Synchronous CDMA Systems

Overview This paper computes achievable rates for synchronous Code-Division Multiple-Access (CDMA) systems and studies the associated coding-spreading tradeoff problem using these results. Random spreading sequences are assumed and the computed achievable rates are averaged over ensembles of spreading sequences. Unlike most prior work which analyzed the spectral efficiency of large CDMA systems under Gaussianity assumptions (inputs and multi-user interference), no such assumptions are made. In order to display the coding-spreading tradeoff, the required minimum SNR are plotted for reliable transmission as a function of information rate.

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.
