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.

高清電子書-C++ Primer Plus, 第6版英文版 1438頁Learning C++ is an adventure of discovery, particularly because the language accommodates several programming paradigms, including object-oriented programming,
generic programming, and the traditional procedural programming.The Fifth edition of
this book described the language as set forth in the ISO C++ standards, informally
known as C++99 and C++03, or, sometimes as C++99/03. (The 2003 version was
largely a technical correction to the 1999 standard and didn’t add any new features.)
Since then, C++ continues to evolve.As this book is written, the international C++
Standards Committee has just approved a new version of the standard.This standard had
the informal name of C++0x while in development, and now it will be known as
C++11. Most contemporary compilers support C++99/03 quite well, and most of the
examples in this book comply with that standard. But many features of the new standard
already have appeared in some implementations, and this edition of C++ Primer Plus
explores these new features.
C++ Primer Plus discusses the basic C language and presents C++ features, making
this book self-contained. It presents C++ fundamentals and illustrates them with short,
to-the-point programs that are easy to copy and experiment with.You learn about
input/output (I/O), how to make programs perform repetitive tasks and make choices,
the many ways to handle data, and how to use functions.You learn about the many
features C++ has added to C, including the followi
