Beschreibung / Abstract
In this thesis, rate-splitting based interference exploitation has been investigated in order to bridge theory and practice. The results shows that conventional detection-decoding techniques cannot provide desirable results within a reasonable complexity and thereby substantially reduce interference mitigation gains. A multi-layer rate splitting scheme is proposed to deal with this obstacle. This multi-layer rate splitting scheme can approach or achieve the same
maximum sum rate as that achieved by joint decoding.
