Abstract: This paper proposed a full duplex relay strategy based on threshold of the signal to noise ratio from source node to relay nodes (SR) and the minimum self-interference of relay nodes,and constructed an improved adaptive full duplex relay system through combining with the full duplex relaying strategy based on the maximum of signal to noise ratio from source node to relay nodes.Under the condition of equal power allocation and using DF protocol forwarding,the outage probability of the proposed full duplex relay system was analyzed.The results show that the outage probability of the proposed full duplex relay strategy is lower than that of an adaptive half duplex relay strategy.It is also lower than that of a full duplex relay strategy based on the maximum of signal to noise ratio from source node to relay nodes when the self-interference signal is strong and the signal to noise ratio of SR is large.The proposed adaptive full duplex relay system will use relay strategy of the full duplex relay system based on the maximum of signal to noise ratio from source node to relay nodes to maintain good outage performance when the self-interference signal is weak.
