随着当今移动通信中各种多媒体应用的出现，无线通信系统对更高数据速率的需求已变得不可避免。多输入多输出 (MIMO) 天线是用于支持无线通信中所需的更高数据速率的技术之一。然而，蜂窝通信的能源效率最近引起了人们的广泛兴趣。能源效率指标将为比较提供一个标准，并为实现蜂窝网络绿色通信的目标提供途径。本文研究了适用于第三代合作伙伴计划 (3GPP) 长期演进 (LTE) 的不同 MIMO 传输方案的能效，并将它们与彼此以及 SISO 传输进行了比较。推导并讨论了各种 MIMO 方案的能耗等级 (ECR)。
The demand for higher data rates in wireless communication systems has become inevitable with the availability of diverse range of multimedia applications in mobile communications today. Multiple Input Multiple Output (MIMO) antennas is one of the technologies utilized to support the required higher data rates in wireless communications. However, energy efficiency in cellular communications has generated lots of interest recently. Energy efficiency metrics will provide a yardstick for comparison and a pathway towards achieving the objectives of green communications in cellular networks. This paper investigates the energy efficiency of different MIMO transmission schemes applicable in 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) and compares them with each other and SISO transmission. The Energy Consumption Rating (ECR) of the various MIMO schemes are derived and discussed.
