Abstract

Automatic-repeat request (ARQ) protocols employing slow frequency hopping over Gilbert-Elliott fading channels are investigated. Throughput efficiency formulae for the three basic ARQ schemes, “stop-and-wait” (SW),“go-back-N” (GBN), and “selective-repeat” (SR), are obtained, and the improvement in throughput efficiency due to slow frequency hopping is examined. The work has application to TDMA architectures and packet data services for third generation wireless networks
