OFDM Code-Division Multiplexing With Pre-Equalization for Mobile Communications

Overview In this paper, the potential of orthogonal frequency-division multiplexing-code-division multiplexing (OFDM-CDM) combined with the pre-equalization is investigated. The code-division multiplexing (CDM) component within an orthogonal frequency-division multiplexing (OFDM) system enables additional diversity in frequency- and time-selective mobile radio channels. While, by applying pre-equalization at the OFDM-CDM transmitter the task of equalization at the receiver can be completely avoided. Different pre-equalization techniques are investigated, and it is shown that pre-equalized OFDM-CDM systems can achieve promising performance in fading channels.

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.
