| 摘 要： | 在多用户放大转发双向中继通信网络中,文章分别基于两种信道状态信息(CSI)反馈模式:无CSI反馈和存在基站-中继链路CSI反馈,推导了中断概率闭合表达式,并提出一种最优用户选择方法使平均和速率最大化.仿真结果显示,CSI的反馈有助于系统性能的提高,所提的用户选择方法能显著提升系统和速率.

| Abstract: | In multiuser amplify-and-forward two-way relay communication networks,the closed form expressions of outage probability are derived under two channel state information(CSI) feedback modes,i.e.,no CSI feedback and base station-relay link CSI feedback,and an optimal user selection scheme is proposed to maximize the expected sum rate.The simulation results show that the system performance with CSI feedback is superior to that without CSI feedback,and the proposed user selection scheme can dramatically improve ... |
