Abstract: The scheme of selective repeat automatic repeat request (SR-ARQ) with adaptive modulation (AM) systems was discussed. And the throughput expression was derived. Theoretic analysis and numerical calculation show that ARQ combined with AM will have a better performance than that of conventional ARQ schemes even if in different Nakagami fading channels.

Key words: automatic repeat request, adaptive modulation, throughput, Nakagami fading channel
