摘要：

针对频谱共享认知无线电网络中次用户容量最大化问题，提出了一种联合最优功率分配和感知门限选择的方法。因此，最优功率分配（OPA）和频谱感知（SpSe）被认为是在SS CRNs模型。结果表明，这种联合优化选择通过最大化SU的容量来提高SU的性能。

英文摘要：

We propose a joint optimal power allocation and sensing threshold selection for capacity maximization at the secondary user (SU) in spectrum sharing (SS) cognitive radio networks (CRNs). Hence, both optimal power allocation (OPA) and spectrum sensing (SpSe) is considered in the SS CRNs model. The obtained results show that such a joint optimal selection improves the performance of the SU by maximizing its capacity.
