Abstract: In this study, a cross-layer design which combines
adaptive modulation and coding (AMC) and hybrid automatic repeat
request (HARQ) techniques for a cooperative wireless network is
investigated analytically. Previous analyses of such systems in the
literature are confined to the case where the fading channel is
independent at each retransmission, which can be unrealistic unless
the channel is varying very fast. On the other hand, temporal channel
correlation can have a significant impact on the performance of
HARQ systems. In this study, utilizing a Markov channel model
which accounts for the temporal correlation, the performance of
non-cooperative and cooperative networks are investigated in terms of
packet loss rate and throughput metrics for Chase combining HARQ
strategy.
