Description
Research presented in this thesis develops a mainly theoretical basis and computer
models for enhancing the throughput of multi-user wireless communication networks.
The cross-layer combination of an adaptive modulation and coding (AMC) scheme at the
physical layer and the use of automatic repeat request (ARQ) retransmi ssions at the data
link layer is integrated into a scheduling framework for multi-user networks. Scheduling
algorithms incorporating retransmission diversity are derived for three cases of typical
network traffic: best-effort, non-realtime, and realtime. For each case, numeric computer
si mulations of wireless communications over Nakagami-m block fading channels are
developed to examine the effectiveness of the formulated schemes.
