Author Description

The unification of connectivity and mobility requires to transmit real-time multimedia data reliably with high speed and low latency. This demands new approaches to the design and analysis of wireless networks. In this context, multiple antenna architectures are a promising solution which provide wireless systems with a high degree of functionality, adaptability, capacity, and robustness. However, efficient use of these systems is possible only by solving a number of critical problems. In this manuscript, we focus on coding performance and capacity analysis of multiple antenna systems. Knowledge in these areas provides us with guidelines into analysis and design of systems, reveals inherent limitations, pinpoints problems and opportunities for improvement, and also allows for rigorous argument and justification of observations. In this regard, performance limits and error bounds for space-time codes are discussed, along with guidelines for systematic design of space-time codes in the presence of the channel correlation profile. Moreover, a unified approach to the capacity analysis of multiple antenna channels is presented.
