Abstract
This work studies the impact of a specific channel time correlation model on the link-level performance of a coded OFDM system that uses iterative channel estimation. When the main focus of extensive simulation campaigns is to measure the overall system performance, it would be desirable to implement low-complexity algorithms that replace the well-agreedupon Clarke's model to mimic the time evolution of the multipath fading process. The main scope of this paper is to investigate suitable scenarios in which this approach is allowed, by using both theoretical analysis and numerical simulations. © 2011 EURASIP.File in questo prodotto:
