摘要：
In this contribution the robustness and reliability of a broadband single carrier MIMO transmission in significantly changing channels is under investigation. Real field measurement data is used to show the effectiveness and influence of the proposed MIMO link adaptation scheme, where for different transmit antennas variable signal modulations are considered. Furthermore the performance of two different concepts, the multi level bit interleaved coded modulation (MLBICM) and the common BICM, for Turbo MIMO Equalization with variable higher modulations is compared. It was found, that the temporal and spatial multipath structure is strongly influencing the robustness of the MIMO transmission. An adaptation of the signal modulation per antenna improves the reliability on the signal detection.
