In this chapter, we study the fundamental principles of MIMO transmission and illustrate its performance advantages. We first introduce the flat fading MIMO channel model. Then, we present several MIMO transmission strategies exploring the diversity benefit inherent to MIMO channel. After that, we investigate the capacity potential of MIMO channel and study MIMO transmission strategies extracting the spatial multiplexing gains. The chapter is concluded with a characterization of the diversity-multiplexing trade-off.
