Abstract :
In this paper, we consider frequency-selective adaptation from a link and a MAC layer perspective. In particular, we focus on the question of how to combine forward error correction with adaptive modulation and hybrid ARQ. The link adaptation scheme is then fitted into a packet-oriented multi-user OFDM system with a dynamic scheduler.
