Timing Synchronization of the WIND-FLEX OFDM Prototype

Overview Timing synchronization of an early WIND-FLEX prototype is discussed in this paper. Simulation results for different low-complexity timing synchronization metrics are given in an AWGN (Additive White Gaussian Noise) channel. Simulations take into account frame detection via a threshold comparison followed by symbol timing estimation using a maximum search. Training symbols are fixed. A novel low-complexity metric reaches equal or better results than the Maximum Correlation (MC) metric, if it requires optimal timing. Furthermore, nearly identical performance as with the Maximum Normalized Correlation (MNC) metric is achieved, if threshold 0.4 or 0.6 is used.

Peter Cochrane's Blog: Start-up failures

The other key mechanisms of failure are generally under-funding, bad timing and competition. I can't give a comprehensive analysis here but I look at timing as being too early or too late for a market.

Are your systems falling down on resiliency?

Furthermore, research shows a strong correlation between the consideration of resiliency early in a project and reduced software failures. Obviously, the business has a say on functionality, timing and audience.

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.
