However, too many cooperative users will make the whole sensingtime unbearably long and consume huge system resource.
但是过多的认知用户参与协同检测，会使整个认知无线电网络的灵敏度降低，同时也会造成巨大的系统开销。

In cooperative spectrum sensing networks, the performance of the spectrum sensing is influenced by the sensingtime and data fusion scheme.
在协作频谱感知网络中，感知时间和数据融合准则均影响着感知性能。

And then an optimum sensingtime and transmitted power allocation was proposed by making use of the approximate outage probability formulation as cost function.
