Abstract
In this paper, we investigate an OFDM adaptive modulation system for multipath wireless channels that is suited for practical hardware implementation. The design of the adaptive scheme takes into account the feedback delays introduced by the components of an OFDM transceiver. Performances are investigated when employing OFDM channel estimation and a non-ideal OFDM feedback channel.
