Channel Estimation for OFDM Systems in Case of Insufficient Guard Interval Length

Overview This paper presents a novel method used to channel estimation for OFDM systems in case of insufficient guard interval length. This method suppresses additive noise and interference components by averaging the estimated channel coefficients in the time direction. The channel coefficients obtained after time averaging must be added to an adjusting coefficient to approach the true channel. This method improves the channel estimation performance significantly with the assumption that the channel is time-invariant or slowly time-varying.

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?
