Phase Noise Suppression in OFDM Using a Kalman Filter

Overview The performance of an OFDM system can be strongly degraded by the presence of random phase noise especially if a system design targets high data rates at high carrier frequencies. Phase noise causes constellation rotation, the so called Common Phase Error (CPE), and InterCarrier Interference (ICI). This paper introduces an algorithm for pilot based CPE estimation using an Extended Kalman Filter (EKF). A method for calculating power of ICI needed for EKF operation but also important in general for the characterization of phase noise influence on OFDM transmission, is presented as well.

Opinion: We'll pay for ID cards

You need to start with projects that are robust enough to resist the interference and abuse from politicians, technologists and civil-servants without jamming. Incidentally, I heard at Westminster today that the NPfIT has revised its timetable to...

Physicists put huge computing grid through its paces

UK particle physicists have started the next phase of testing for the world's largest computing grid. The service phase of the test began earlier this month and will take three months. By 2007, this will have increased 10-fold as the grid gears up...

Urban wireless networks set to surge

Nonyelu said: "It's relatively small but the infrastructure that's in place is designed to scale to cover the whole city so we're just discussing the next phase, which is to begin to expand from that initial pilot area out to the rest of the city.

High speed TGV trains get online

The service, which is still in its trial phase, offers TGV passengers with wi-fi-enabled devices unrestricted access to the internet at 2Mbps download and 512Kbps upload rates. The system automatically switches to the wi-fi terminals - with a...

SMS snitch pilot targets knife crime in schools

The text pilot enables youngsters to anonymously report classmates or other youths they suspect of carrying knives to anti-crime charity Crimestoppers UK. A wave of knife crime violence has claimed the lives of scores of teenagers in London this...

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.
