Major-auxiliary Cooperative Two-way Relay Scheme In The Ground Wave Transmission Of High-frequency Communication

11848

Due to the high flexibility and the large communication coverage of the high-frequency (HF) communication, it is widely used in the fields of military and civil. In view of the ground wave transmission of HF communication, the paper proposes the major-auxiliary cooperative two-way relay scheme. Its main idea is that adopting the auxiliary relay to assist the major relay for receiving two independent signals, then the major relay may decode-and-forward (DF) the information. Thus the outage performance can be improved. In this paper, we not only analysis the outage probability of the scheme which this paper proposed, but also discuss the effect of power allocation on the outage performance. Theoretical research and simulation results show that the scheme can reduce the outage probability of the ground-wave communication. And the more pairs of relay nodes in the scheme, the outage probability is lower.
