Single-user MIMO

In this chapter we study the single-user MIMO channel which is used to model the communication link between a base station and a user. We explore in more detail the fundamental results that were briefly described in the previous chapter. We derive the open-loop and closed-loop MIMO channel capacities and describe techniques for achieving capacity including architectures known as V-BLAST and D-BLAST. We also describe classes of suboptimal techniques such as linear receivers, space-time coding for transmitting a single data stream from multiple antennas, and precoding when there is limited knowledge of CSI at the transmitter.
