摘要

MIMO是一种利用发射器/接收器上的多个天线来提高无线系统的吞吐量、容量和覆盖范围的技术。与信号处理算法简单的MIMO相比，基站天线数量多的大规模MIMO的频谱效率提高了10倍以上。大规模MIMO具有增强容量，频谱和能源效率的优点，并且可以通过使用低成本和低功耗组件来构建。尽管具有潜在的优势，但本文也总结了大规模MIMO面临的一些挑战，如天线空间相关和相互耦合以及非线性硬件损伤。在大规模MIMO中遇到的这些挑战揭示了需要进一步研究的新问题。

Massive MIMO for Fifth Generation (5G): Opportunities and Challenges

MIMO is a technology that utilizes multiple antennas at transmitter/receiver to improve the throughput, capacity and coverage of wireless system. Massive MIMO where Base Station is equipped with orders of magnitude more antennas have shown over 10 times spectral efficiency increase over MIMO with simpler signal processing algorithms. Massive MIMO has benefits of enhanced capacity, spectral and energy efficiency and it can be built by using low cost and low power components. Despite its potential benefits, this paper also summarizes some challenges faced by massive MIMO such as antenna spatial correlation and mutual coupling as well as non-linear hardware impairments. These challenges encountered in massive MIMO uncover new problems that need further investigation.
