Randomly Spread CDMA: Asymptotics Via Statistical Physics

Overview This paper studies randomly spread code-division multiple access (CDMA) and multiuser detection in the large-system limit using the replica method developed in statistical physics. Arbitrary input distributions and flat fading are considered. A generic multiuser detector in the form of the posterior mean estimator is applied before single-user decoding. The generic detector can be particularized to the matched filter, decorrelator, linear minimum mean-square error (MMSE) detector, the jointly or the individually optimal detector, and others.

Signing up the competition - have digital signatures met their match?

It certainly takes longer to detect a hack than a virus, because viruses are spread between machines and they usually crash them. Take hacker detection, which has become a crucial business issue as more money is made online and corporate Web sites...

Intel develops chip error detection tool

The error is expected to most easily affect the sub-0.25 micron process technology as alpha particles from the packaging around chips intrude on the technology. Intel has developed a simulation tool to test for so-called 'soft errors' that could...

IBM aims to get smart about artificial intelligence

Artificial intelligence in a sense will function like a filter. The theory underlying UIMA is the Combination Hypothesis, which states that statistical machine learning - the sort of data-ranking intelligence behind search site Google - syntactical...

Who knows more about your network - you or the cyber-criminals?

Hopefully companies have detection in place, because if they don't it just becomes another way for viruses to spread," said Gullotto. As a topical example of how viruses can spread by peer-to-peer, the recent Coronex worm copies itself into the...

Will future networks be faster than light-speed?

After they were moved apart, most of the photons reflected off the first prism they encountered and were picked up by a detector. Although these photons had travelled a longer distance, they arrived at their detector at exactly the same time as the...

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.

IBM Information Server Change Data Capture

In today's fast-paced world, access to real-time data has never been more important. To be successful, organizations need to be able to report and analyze corporate data quickly and easily, regardless of what applications created the data, what platform they're running on, or what database they're stored in.
