A Delayed Multiple Copy Retransmission Scheme for Selective Repeat ARQ in Correlated Fading Channels

摘要

In this paper, we propose a delayed multiple copy retransmission (D-MCR) scheme. By using Markovian analytic method we present the performance evaluation of the D-MCR scheme in correlated fading channels. Both effective throughput and number of retransmissions are derived. The analytic results show that the D-MCR scheme can improve the performance greatly, especially in slow fading channels.
