讨论协作通信的复用增益的优势。首先，给出多天线中继网络之间传输速率和中断概率的基本权衡的新解释；然后讨论协作复用增益获得任何有限SNR的可能。在全双工的中继网络中，中继不仅能提供可靠的链路连接，还能提高更高的频谱效率。结果表明，在分集一复用权衡对任何有限的信噪比值下，复用增益能显著影响系统性能。

Previous work on benefits of such techniques. cooperative communications has concentrated primarily on the diversity This paper, instead, considers the multiplexing benefits of cooperative communications. First, a new interpretation on the fundamental tradeoff between the transmission rate and outage probability in multiple-antenna relay networks is given. It follows that multiplexing gains can be obtained at any finite signal-to-noise ratio （SNR）, in full-duplex multiple-antenna relay net- works. Thus, relaying can offer not only stronger link reliability, but also higher spectral efficiency. It is shown that this power gain can significantly affect the system diversity-multiplexing tradeoff for any finite SNR value.
