4. Introduction
 Multiple Input Multiple Output (MIMO) is an antenna technology for wireless communications in which
multiple antennas are used at both the source (transmitter) and the destination (receiver).
 MIMO has been treated as an emerging technology to meet the demand for higher data rate and better cell
coverage even without increasing average transmit power or frequency bandwidth, since it was proved that
MIMO structure successfully constructs multiple spatial layers where multiple data streams are delivered on
a given frequency-time resource and linearly increases the channel capacity.
 MIMO technology has evolved from traditional single antenna communication to multi-user MIMO
scenarios, to the possible multi-cell MIMO networks of the future.
 In Long Term Evolution (LTE), MIMO technologies have been widely used to improve downlink peak rate,
cell coverage, as well as average cell throughput.
 LTE adopted various MIMO technologies including Transmit Diversity, Single-User (SU) MIMO, Multi-
User (MU) MIMO, Closed Loop Rank-1 Precoding, and Beam-forming.
 There are two user schemes used in LTE-MIMO. They are:
• Single-user schemes
• Multi-user schemes
