由于智能移动的设备上的数据需求量大的应用的使用增加，对数据流量的需求巨大。这导致了蜂窝网络的扩展和升级，这增加了能源成本并产生了环境问题。分布式天线系统（DAS）被应用于经由连接到位于小区中心的基站的地理上分布式的天线元件（DAE）来增强小区的覆盖。在本文中，DAS被提出作为一种网络解决方案，以满足不断增长的容量需求，同时解决与蜂窝网络操作相关的能源效率（EE）和环境问题。最大比传输（MRT）和分数频率复用（FFR）被应用于计算下行链路遍历频谱效率（SE），EE和能量消耗比（ECR）。Nakagami-m衰落和对数正态跟踪。我们的研究结果表明，DAS使用MRT和FFR增加了频谱和能量效率的网络相比，一个基本的蜂窝网络系统。
There is a huge demand for data traffic caused by increased usage of data-hungry applications on smart mobile devices. This has resulted into cellular network expansion and upgrade that have increased energy costs and generated environmental concerns. Distributed antenna systems (DAS) are applied to enhance the coverage of the cell via geographically distributed antennas elements (DAEs) which are connected to the base station that is located at the centre of the cell. In this paper, DAS is proposed as a network solution to fulfill increasing capacity demands while addressing the energy efficiency (EE) and environmental concerns associated with cellular network operation. Maximum Ratio Transmission (MRT) and Fractional Frequency Reuse (FFR) are applied to calculate the downlink ergodic spectral efficiency (SE), EE and energy consumption ratio (ECR). Nakagami-m fading and log-normal shadowing are considered. Our results demonstrate that DAS using MRT and FFR increases the spectral and energy efficiency of the network compared to a basic cellular network system.
