Abstract
In the paper, the Adaptive all Cooperative (AAC) scheme is raised to bring significant improvements in cooperative system property, which is combined self-adaption signal modulation with automatic repeat request. Then we develop the Adaptive scheme to the Adaptive Greedy Cooperative (AGC) scheme using greedy strategy selection, which can obtain the characteristics of cooperative system significantly enhanced with the same cooperative nodes. However, the Adaptive greedy cooperative (AGC) is more sensitive than the AAC under the delayed feedback. We calculated the closed relationship expression between the probability of abnormal outage for AAC and AGC. Considering delayed feedback, we also analyze outage probability of AAC and AGC frames with different retransmission times, delayed time and cooperative users.
