提出一种协作通信中的全/半双工中继的混合方案。分析计算了在解码转发（DF）下等功率分配时的中断概率的理论表达式；对比了考虑直传链路和不考虑直传链路时的系统性能，指出考虑了直传链路所获得的性能增益；并通过计算机对理论分析进行仿真。结果表明：相对于单一的全双工（或者半双工）选择方案，提出的混合双工系统具有更低的中断概率、更好的系统性能，并且随着潜在中继数目的增加，系统中断概率越低。

This paper proposes a hybrid duplex mode in cooperative communication, which is the hybrid of full duplex and half duplex. It analyses and calculates the theoretical expression of the outage probability in DF. It compares the sys-tem performance between with a SD link and without, and it proposes the way with SD link is better. Via the computer simulation, it finds that the hybrid duplex in this paper has a lower outage probability and a better system performance. It also finds that more relays more better.
