Joint Channel and Frequency Offset Estimation for OFDM Systems

Overview In this paper, a joint channel and frequency o set estimation algorithm is proposed. The time variation of the effective Channel Impulse Response (CIR) due to frequency o set is tracked using a channel tracker. This variation is used to estimate the frequency o set as well as the actual time-invariant channel coefficients. The proposed method does not require transmission of repetitive pattern, thus allowing a covert communication for applications where security is important. It can be used to estimate not only the fractional part but also the integer part of the frequency o set. The proposed algorithm is tested using computer simulations.

Peter Cochrane's Uncommon Sense: The right technology for the right job

At a modest estimate, over $200m has been expended to date and no one has been successful in transmitting significant amounts of data over power cables to the home. This alone precludes transmission of high-speed data over significant distances.

Mobiles could get atomic clocks

Atomic clocks long have provided the most accurate measurements of time and frequency but also have traditionally been large - up to two meters in height - as well as power-hungry and expensive to build, according to NIST.

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.
