| 1 | 异构认知网中基于能效的协作技术研究显示文摘针对异构认知网络场景,提出了一种主次系统'双赢'的高能效协作通信机制。在满足主次系统'双重'速率Qo S要求下,该机制允许次级用户在接入主系统协助主用户传输数据的同时,换取一部分授权频谱资源来实现自身数据在异构网中的传输分流,以此提升次级能效。本文研究了该机制的次级加权能效最大化非凸资源优化问题,结合参数化的分式规划算法和黄金分割法提出了一种资源分配的迭代算法。仿真结果表明,所提机制在不降低主用户通信性能的情况下,提升了次级系统传输能效,实现了主次系统传输'双赢'的目的。 | 冯立 邝育军 代泽洋 付新川 | 2017 | 电子科技大学学报2017，46，5： | 2 |
| 2 | Outage Performance of Cognitive AF Relay Networks with Imperfect CSI Based on Geometrical Analysis显示文摘This paper studies the outage performance of a cognitive Amplify-and-forward(AF) relay network subject to Rayleigh fading.Under the condition of imperfect Channel state information(CSI) estimations of the links from the secondary system to the Primary user(PU),the closed-form upper and lower bounds of the outage probability are derived through a geometrical analysis method.An asymptotic analysis of the outage probability is also derived in the high Signal-to-noise ratio(SNR)regime to gain additional insights on the system.The simulation results corroborate our theoretical analysis,and the effectiveness of the geometrical analysis method is verified with the conventional approach as a benchmark.The asymptotic results are very tight with the analytical lower bound in the high SNR regime.It also can be observed from the simulation results that the impact of the number of relays as well as the imperfect CSI on the outage probability and the diversity order. | LIU Shuai SUN Dechun LIU Zujun YI Kechu YANG Hong WANG Kan | 2017 | Chinese Journal of Electronics2017，26，5： | 0 |
