Chapter 3
Space Time Codes and MIMO Transmission
3.1 Introduction
Having introduced the MIMO wireless channel, and the remarkable capacities that are in principle available to exploit it, in this chapter we introduce some of the practical techniques that can be used to transmit data upon it, hence realizing this capacity.
In particular, we discuss the concept of space-time coding. This is in its own right one of the most important transmission techniques, but we will also use it as a general mathematical tool to analyze the performance of any transmission technique for the MIMO channel. As such we will apply it to other transmission techniques which are not usually thought of as space-time codes, notably spatial multiplexing.
However, ...
