为了优化协作通信系统的性能 ,提出了一种基于信道容量增益的中继节点选取策略 ,并在此基础上提出了源节点和中继节点最优功率分配算法. 协作通信 中继节点选取 功率分配 凸优化(A joint optimization st rategy for relay selection and power allocation is proposed to optimize the performance of cooperative communication system.cooperative communication relay selection power allocation convex optimization)

说明：  利用通信系统中调制信号的循环平稳特性,对频谱空洞进行检测,提升频谱感知技术在低信噪比下的性能。实验结果表明:与传统能量检测方法相比,采用循环特征检测方法改善了认知无线电中频谱空洞的检测能力。(Based on the cyclostationarity of modulation signals, spectrum hole is detected, aiming at the improve- ment of the performance of spectrum sensing in low SNR situation. The results show that comparing with the tra- ditional energy detection technique, cyclostationarity-based spectrum sensing technique has greatly improved the detective ability in cognitive radio.)
