本文利用一种新的数学方法研究了分布式天线系统下行链路各态历经频谱效率（ESE）和能量效率（EE）之间的折衷关系。应用最大比传输（MRT）和分数频率复用（FFR），并考虑复合Nakagami-m衰落和对数正态阴影。使用所提出的分析方法，大大简化了使用MRT的FFR模式下DAS的性能评估。
This letter investigates the trade-off between the downlink ergodic spectral efficiency (ESE) and the energy efficiency (EE) of distributed antenna systems (DAS) by using a new mathematical approach. Maximum ratio transmission (MRT) and fractional frequency reuse (FFR) are applied and composite Nakagami- m fading and log-normal shadowing are considered. The performance evaluation of DAS in FFR mode using MRT is greatly simplified using the proposed analytical approach.
