研究了认知无线中继网络在衰落环境下的中断性能，在这种环境下，包括源和中继在内的次要用户可能会利用许可（主）用户的频段，通过机会主义地以高功率传输，只要它所引起的干扰不被许可方认为是有害的。二级信道性能与主用户受到的干扰之间的关系是量化的。
Investigated is the outage performance of cognitive wireless relay networks in a fading environment, where the secondary users including the source and relays may take advantage of a frequency band of a licensed (primary) user by opportunistically transmitting with high power as long as the interference it incurs is not deemed harmful by the licensee. The relation between the secondary channel performance and the interference inflicted on the primary user is quantified.
