The explosive growth of Multiple Input Multiple Output (MIMO) systems has permitted
for high data rate and a wide variety of applications. Some of the technologies which rely
on these systems are IEEE 802.11, Third Generation (3G) and Long Term Evolution (LTE)
ones. Recent advances in wireless communication systems have contributed to the design of
multi-user scenarios with MIMO communication. These communication systems are referred
as multi-user MIMOs. Such systems are intended for the development of new generations
of wireless mobile radio systems for future cellular radio standards. This chapter provides
an insight into multi-user MIMO systems. We firstly present some of the main aspects of the
MIMO communication. We introduce the basic concepts of MIMO communication as well
as MIMO channel modeling. Thereafter, we evaluate the MIMO system performances. Then,
we concentrate our analysis on the multi-user MIMO systems and we provide the reader a
conceptual understanding with the multi-user MIMO technology. To do so, we present the
communication system model for such emerging technology and we give some examples
which describe the recent advances for multi-user MIMO systems. Finally, we introduce
linear precoding techniques which could be exploited in multi-user MIMO systems in order
to suppress inter-user interference.
