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.

Will's Web Watch: Who's been eating my wi-fi?

His tone is more surprised than disappointed. Many users and wi-fi access points are competing for bandwidth on the same channel - often channel 11 - and some channels are becoming critically overloaded while others go unused.

Geography lessons for online retailers

Companies faced a growing choice of channels for connecting customers to products and services. This approach can provide such information as longitude, latitude, connection type and speed, ISP, company name and domain name.

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.
