Expertise:
Wireless Communications, Massive Multiple-Output (MIMO) Systems, Advanced Precoding Techniques, Signal Processing Techniques, Network Data Inference, Data Mining ApplicationsThomas Ketseoglou’s expertise is in the areas of state-of-the-art techniques in wireless communications, data mining, semi-supervised learning and localization techniques. His most recent work focuses on 5G and beyond linear precoder designs for optimized information transfer under reduced complexity and new insights in designing optimal linear precoders, with reduced system complexity. These linear precoding techniques offer semi-optimal information rate (throughput) transmission with relatively low complexity. This is done by selecting the spatially most efficient channel paths for information transmission to each user.
