Simple Doppler Compensation for DVB-T

Overview In the DVB-T system, the Inter-carrier Interference (ICI) caused by the vehicle speed limits the achievable throughput. This paper presents a simple method to improve the performance of the system. This method uses Wiener filters to estimate and track relevant channel parameters. The effect of ICI is mitigated by cancelling the ICI to a sufficiently low level to obtain a reliable detection of 64-QAM modulated signal, using the estimated data and channel parameters.

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?
