协作分集通过使多个节点发送相同的信息来提高无线网络的性能。我们提出了一个中断概率分析的解码和转发系统，有效的在所有的信号噪声比（SNR）。得到了独立同分布（i.i.d.）通道，并提出了两个紧密的下界相关的通道。
Cooperative diversity improves the performance of wireless networks by having several nodes transmit the same information. We present an outage probability analysis for a decode-and-forward system, valid at all signal to noise ratios (SNR). A closed form solution is obtained for independent and identically distributed (i.i.d.) channels, and two tight lower bounds are presented for correlated channels.
