Performance of Channel Estimation Assisted Linear Multiuser Receivers for Downlink CDMA Systems With Long Spreading Codes

Overview With availability of spatial/temporal diversity in the downlink of long code CDMA systems, subspace technique has been shown to be able to estimate channel parameters. Based on the estimated channel, the authors construct three typical linear receivers as ZF, MMSE and RAKE receivers. Due to channel estimation error, those receivers show perturbed performance compared with their optimal counterparts. Their statistical performance is thus analyzed by applying perturbation theory. Those analyses are well supported by numerical results.

Peter Cochrane's Uncommon Sense: Exponential growth - so misunderstood

This led to the linear channel model of economics with a finite population of limited appetite, expectation and money. He was just too linear in his thinking. All are now linked by highly non-linear channels involving fixed and mobile networks...

Peter Cochrane's Uncommon Sense: Logistics on the move

Unfortunately logistics is grossly non-linear and the optimisation of the individual parts on an independent basis always leads to a sub-optimal solution overall. It is necessary with almost all none linear systems to optimize as an overall end-to...

Mobiles could get atomic clocks

In Global Positioning System (GPS) receivers, small clocks could improve the precision of satellite-based navigation systems such as those used in commercial and military vehicles and emergency response networks.

Analysis: CRM - get involved

Retailers especially began to construct huge data warehouses and even small corner shops started launching their own loyalty card schemes. Unfortunately, no other great insights emerged and the beer-nappy theory turned out to be an urban myth anyway.

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.
