In this paper, a joint PHYsical-layer and Protocol- level simulation analysis of Adaptive Modulation (AdMod) including the specific signaling is carried out. AdMod is a well-known technique which can be applied to an Orthogonal Frequency Division Multiplexing (OFDM) system, which variably adapts the modulation scheme to the Signal-to-Noise-Ratio (SNR) on a per sub-carrier basis. To decide if AdMod is capable of introducing an overall system enhancement, its performance will be determined for a HIPERLAN/2 system in the presence of a frequencyselective and time-varying radio channel. Furthermore, real system effects like performance degradations due to preamble-based channel estimation, zero-forcing equalization and the impact of non-perfect bit-loading are considered.
