Unified approach for optimisation of single-user and multi-user multiple-input multiple-output wireless systems (2008)
Abstract / truncated to 115 words
Multiple-input multiple-output (MIMO) systems will be applied in wireless communications in order to increase the performance, spectral efficiency, and reliability. Theoretically, the channel capacity of those systems grows linearly with the number of transmit and receive antennas. An important performance metric beneath capacity is the normalised mean square error (MSE) under the assumption of optimal linear reception. Clearly, both performance measures depend on the properties of the MIMO channel as well as on the considered system approach, e.g. on the type of channel state information which is available at the transmitter. It has been shown that even partial CSI at the transmitter can increase the performance. In this thesis, we analyse the performance and design ... toggle 6 keywordsinformation theory – signal processing – MIMO – multiple access channel – broadcast channel – spatial correlation
