Digital communication using multiple-input multiple-output (MIMO) wireless links has recently emerged as one of the most significant technical breakthroughs in modern communications.
This work presents an overview of some important theoretical con­cepts of MIMO systems. After describing the basic ideas of MIMO transmissions, information theoretical concepts like the system capa­city and the mutual information for finite symbol alphabets of some prominent MIMO space-time designs are investigated. An evaluation of the error performance of these designs then leads to a more complete understanding of MIMO system parameters. Finally, the derived system capacity and the error performance is related to the framework of the diversity-multiplexing tradeoff. Each chapter is rounded by a number of simulations to deepen the understanding of the derived theoretical concepts.
