发布时间：2019-07-02 21:04

【摘要】：能量效率(EE,energy efficiency)和频谱效率(SE,spectral efficiency)是无线移动通信系统中两个重要的性能度量.在过去几十年中,工业界和学术界开展了大量的工作来提高频谱效率和系统吞吐量.最近几年由于环境的日益恶化和能量消耗的持续增加,EE变得越来越重要.分布式天线系统(DAS,distributed antenna systems)由于在增强通信链路稳定性、提高系统容量和扩大覆盖范围方面有着极大的优势而受到越来越多的关注,成为下一代无线通信系统中具有竞争力的一项技术.因此在分布式天线系统中研究能耗具有重要的实际价值和意义.针对分布式天线系统,归纳总结了前期研究的高能效的功率分配设计准则、多播MISO(multiple input single output)系统中的高能效传输以及单用户MIMO(multiple input multiple output)的能效优化这3个方面的内容,仿真结果验证了相应提出的能效优化方法的正确性.
[Abstract]:Energy efficiency (EE,energy efficiency) and spectral efficiency (SE,spectral efficiency) are two important performance measures in wireless mobile communication systems. In the past few decades, industry and academia have done a lot of work to improve spectrum efficiency and system throughput. In recent years, EE has become more and more important due to the deterioration of the environment and the continuous increase of energy consumption. Distributed antenna system (DAS,distributed antenna systems) has attracted more and more attention because of its great advantages in enhancing the stability of communication links, improving system capacity and expanding coverage, and has become a competitive technology in the next generation wireless communication system. Therefore, it is of great practical value and significance to study energy consumption in distributed antenna systems. Aiming at the distributed antenna system, the energy efficiency power allocation design criteria, the energy efficiency transmission in the multicast MISO (multiple input single output) system and the energy efficiency optimization of the single user MIMO (multiple input multiple output) system are summarized. The simulation results verify the correctness of the corresponding energy efficiency optimization method.
