Time-Domain and Frequency-Domain Per-Tone Equalization for OFDM Over Doubly-Selective Channels

Overview This paper proposes new time-domain and per-tone frequency-domain equalization techniques for OFDM transmission over time- and frequency-selective channels. The paper presents one mixed time- and frequency-domain equalizer and one per-tone frequency-domain equalizer. The Mixed Time- and Frequency-domain EQualizer (MTFEQ) consists of a one-tap Time-Varying (TV) Time-domain EQualizer (TEQ), which converts the doubly-selective channel into a purely frequency-selective channel, followed by a one-tap Frequency-domain EQualizer (FEQ), which then equalizes the resulting frequency-selective channel in the frequency-domain. The per-tone frequency-domain equalizer (FPTEQ) is then obtained by transferring the TEQ operation to the frequency-domain.

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.
