摘要

对基于机会调度的上行两跳认知放大中继蜂窝网络的中断性能进行研究，导出了该系统的中断概率封闭表达式和高信噪比下的中断概率近似表达式。该系统中有多个源节点，研究表明，通过选择最优的次用户进行信息传输，系统中断性能可得到改善。仿真验证了理论推导的正确性。

Abstract

The exact and asymptotic closed-from expressions for the outage probabilities (OPs) of uplink dual-hop cognitive amplify-and-forward (AF) relay cellular networks with opportunistic secondary user (SU) scheduling are investigated. Multiple SUs are involved in this networks.By opportunistically scheduling the best SU to transmit

the performance of uplink cognitive AF relay cellular networks is improved. Simulation results are presented to validate the theoretical analysis.
