Manuscript Abstract
Massive multiple-input multiple-output (MIMO) has been regarded as a promising technique for the next generations of wireless communication networks. Massive MIMO refers the idea of equipping cellular base-station (BS) with a very large number of antennas that can mainly improve either the spectrum efficiency or energy efficiency. The network capacity is also improved to satisfy the increasing requirements of high rate of wireless communication networks in which different kinds of smart elements are integrated. This paper reviews the main advantageous points of massive MIMO ,and also shows the existing challenges that need to be solved for a better performance can be achieved. The capacity, the energy efficiency and the spectral efficiency are briefly analyzed together with other advantages. The massive MIMO antenna configurations, the pilot contamination, the channel models and the signal processing complexity are also mentioned as challenges. Explanations are also provided accordingly to each problems. Some opening topics are addressed to be focused in order to improve the network with massive MIMO.
