Delay statistics of cooperative automatic repeat request over wireless networks with link adaptation
Yanli Liu, Shengye Huang, Chun Chen · International Journal of Communication Systems · 2012
SUMMARY This paper proposes a method to analyze the delay distribution at the transmitter side for cooperative diversity wireless networks with link adaptation, which uses decode‐and‐forward as a relay strategy. The equivalent end‐to‐end channel model is captured by a finite state Markov channel model representing the multiple states of the Nakagami fading channel, and the delay statistics are obtained by using matrix geometry method. Cooperative diversity wireless network has a better delay performance compared with noncooperation wireless network. Copyright © 2012 John Wiley & Sons, Ltd.
