Multiple antennas have proved to be a key enabler for 5G wireless networks. In this talk, we will review a number of fundamentals aspects of multiple input multiple output (MIMO) systems as well as the advanced MIMO techniques to be deployed in high-demanding 5G networks. First, we will discuss multiplexing gain versus diversity gain which is the fundamental trade-off MIMO systems. Then, two techniques, groupwise space time block code (GSTBC) and lattice-reduction based detection, are discussed to demonstrade the achieved diversity/multiplexing gains. By employing a diagonal structure, GSTBC allows affordable complexity at the receiver while still retaining certain diversity gain advantage. The second technique is based on lattice reduction method to enable optimal signal detection at the receiver where high data rate is targeted. Finally, we will discuss the Massive MIMO technique that will be used for 5G architecture, where hundreds or thousands of antennas will be deployed.
