Predictions show that the number of devices with communication capability will rise to 50 billions by 2020, leading to a new paradigm referred to as the Internet-of-Things (IoT). This new paradigm will lead to new and more sophisticated network topologies.As a consequence there is an increasing need for the understanding of the fundamental characteristics of such networks. As multi-way relaying networks resemble instances of such IoT network topologies, they are the subject of investigation of the planned project. In more details, the main goals of of the planned project are designing transmission schemes for multi-way relay channels, optimizing their performance (throughput, power consumption, etc.), and ultimately approaching information-theoretic limits of communication over such channels. As multi-way relaying networks enable exploiting an emerging technique known as physical-layer network coding (PHYNC), the transmission rate of the system can be significantly boosted. Thus, the focus of this project is to study these aspects for the multi-input multi-output (MIMO) multi-way relay channel, and obtain statements about its approximate capacity and trade-offs therein. To this end, tools from signal processing, optimization, and information theory will be used.
