Mimo

多进多出(Mimo)是为极大地提高信道容量,在发送端和接收端都使用多根天线,在收发之间构成多个信道的天线系统。Mimo系统的一个明显特点就是具有极高的频谱利用效率,在对现有频谱资源充分利用的基础上通过利用空间资源来获取可靠性与有效性两方面增益,其代价是增加了发送端与接收端的处理复杂度。大规模Mimo技术采用大量天线来服务数量相对较少的用户,可以有效提高频谱效率。

  • Complex Orthogonal Space-Time Processing

    Multiple-Input Multiple-Output (Mimo) systems have recently been the subject of intensive consideration in modem wireless communications as they offer the potential of providing high capacity, thus unleashing a wide range of applications in the wireless domain. The main feature of Mimo systems is the use of space-time processing and Space-Time Codes (STCs). Among a variety of STCs, orthogonal Space-Time Block Codes (STBCs) have a much simpler decoding method, compared to other STCs

  • Dynamic+Channel+Acquisition

    Multiuser multiple-input-multiple-output (MU- Mimo) systems are known to be hindered by dimensionality loss due to channel state information (CSI) acquisition overhead. In this paper, we investigate user-scheduling in MU-Mimo systems on account of CSI acquisition overhead, where a base station dynamically acquires user channels to avoid choking the system with CSI overhead.

  • Fundamentals+of+Wireless+Communication

    The writing of this book was prompted by two main developments in wireless communications in the past decade. First is the huge surge of research activities in physical-layer wireless communication theory. While this has been a subject of study since the 60’s, recent developments in the field, such as opportunistic and multi-input multi-output (Mimo) communication techniques, have brought completely new per- spectives on how to communicate over wireless channels.

  • Large-scale+Antenna+Systems

    To meet the future demand for huge traffic volume of wireless data service, the research on the fifth generation (5G) mobile communication systems has been undertaken in recent years. It is expected that the spectral and energy efficiencies in 5G mobile communication systems should be ten-fold higher than the ones in the fourth generation (4G) mobile communication systems. Therefore, it is important to further exploit the potential of spatial multiplexing of multiple antennas. In the last twenty years, multiple-input multiple-output (Mimo) antenna techniques have been considered as the key techniques to increase the capacity of wireless communication systems. When a large-scale antenna array (which is also called massive Mimo) is equipped in a base-station, or a large number of distributed antennas (which is also called large-scale distributed Mimo) are deployed, the spectral and energy efficiencies can be further improved by using spatial domain multiple access. This paper provides an overview of massive Mimo and large-scale distributed Mimo systems, including spectral efficiency analysis, channel state information (CSI) acquisition, wireless transmission technology, and resource allocation.
