Space-Time Coding Over I.I.D. Rayleigh Flat Fading Channels
As detailed in the previous chapter, information theory predicts that MIMO channels are able to provide huge gains in terms of reliability and transmission rate. In this chapter,
• we derive practical methodologies to achieve these gains,
• we address how link performance and data rates may be increased through coding across space and time,
• we present two design methodologies motivated by an error rate optimization perspective or by information theory,
• we give an overview of schemes known as space-time codes and we discuss how they perform in terms of both error and transmission rates.
Two groups of encoding schemes are reviewed: space-time block coding (encoding is based ...
