On the Spectral Bitrate Loss of Superimposed Pilot and Preamble Synchronization

Overview In present packet-based wireless OFDM systems, such as IEEE802.11a/g, a preamble technique is used to accomplish the synchronization functions. Although this technique is well-developed, delay and bitrate loss due to preamble motivates to adapt the superimposed pilot technique as an alternative approach for synchronization. This paper studies the spectral bitrate loss due to both techniques and figure out that the length of the superimposed pilot and the ratio of the power of the superimposed pilot to the total power are the most important design parameters to maximize the spectral bitrate of the superimposed pilot technique.

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.
