本文基于接收端最大信干噪比准则，提出了一种分布式天线系统的单传输选择方案，并研究了多小区环境下相应的遍历容量和中断概率。假设信道遭受独立的非相同Nakagami-m衰落，衰落严重性参数m为整数值，我们推导出遍历容量和中断概率的精确闭合形式表达式。蒙特卡洛模拟进行了验证的理论分析。仿真结果表明，所提出的单传输选择方案的遍历容量和中断概率优于覆盖传输方案。版权所有© 2013约翰威利父子有限公司.
In this paper, based on maximum signal‐to‐interference‐plus‐noise ratio criterion at the receiver, we propose a single transmission selection scheme for distributed antenna system and investigate the corresponding ergodic capacity together with outage probability in multicell environment. Assuming that the channels suffer from independent non‐identical Nakagami‐m fading with integer values of fading severity parameter m, we derive exact closed‐form expressions for the ergodic capacity and outage probability. Monte‐Carlo simulations are carried out to validate the theoretical analysis. Simulation results show that the ergodic capacity and outage probability of the proposed single transmission selection scheme outperform that of blanket transmission scheme.
