Rate-splitting multiple access (RSMA) is a novel multiple access framework that serves multiple users while maximizing the efficiency of limited wireless resources. By generalizing and unifying conventional strategies such as spatial division multiple access (SDMA) and non-orthogonal multiple access (NOMA), RSMA enables robust performance gains across a wide range of interference and network conditions. In CORE Lab., we develop signal processing and optimization algorithms to advance communication systems and enhance the practicality of RSMA. 

Non-terrestrial network (NTN) communications enables wireless connectivity through aerial and spaceborne platforms such as UAVs and satellites. With their ability to provide large-scale coverage and extend network availability to underserved regions, NTN systems are emerging as a major trend in future communication networks and are actively studied in both academia and industry. In CORE Lab., we develop advanced communication algorithms that enhance system performance by leveraging the unique capabilities of NTN architectures. 

AI/ML-based communication techniques are emerging as key enablers for learning hidden structures in wireless systems that are not easily captured by conventional theoretical analysis. By flexibly adapting to nonlinear and complex environments, AI/ML approaches provide powerful tools for addressing challenging communication problems under practical constraints. In CORE Lab., we develop algorithms that leverage AI/ML models to tackle complex communication systems and enhance their performance and robustness. 

Reconfigurable communication technologies introduce new degrees of freedom to wireless systems by enabling physical reconfiguration of antennas and the propagation environment. Emerging architectures such as movable antennas, fluid antennas, tri-hybrid communication systems, and reconfigurable intelligent surfaces (RISs) allow flexible manipulation of electromagnetic waves beyond conventional array-based communications. These technologies open new opportunities for improving coverage, interference management, and system efficiency. In CORE Lab., we develop advanced algorithms to reveal the hidden capabilities of reconfigurable communication systems.
