碩士 === 國立成功大學 === 電腦與通信工程研究所 === 103 === Massive multiuser-multiple-input-multiple-output (Massive MIMO) brings significantly improvement in channel capacity and energy efficiency via placing a great number of antennas at base station (BS). But in the real system, it is impossible to increase the number of antennas without limit. Therefore, we consider a system with large number of antennas in fixed physical antenna space, and use simple linear precoding (i.e. Zero-Forcing Precoding, Match-Filter Precoding), discuss the relationship to the physical space, correlation and channel capacity. In this thesis, we also compare the performance of different precoding method by user selection to improve the channel capacity.
