摘要
Abstract
The explosive growth of wireless data traffic in future fifth generation(5G) mobile communication systems has pushed researchers to develop new disruptive technologies.Massive multiple-input multiple-output(MIMO),as one of 5G key technology candidates,can increase tenfold spectral efficiency and save the transmit power greatly through the use of a large excess of service antennas in base stations over active terminals.This paper presents an overview of massive MIMO with regard to system models and theoretical performance,channel measurement and modeling,channel state information acquisition,transmission techniques,experimental and test results.It also discusses several future research topics.关键词
