   Sammanfattning : The last decade has seen the emergence of a new research theme - the study of the resources Nexus. The “Nexus” refers to considering the functioning of several systems simultaneously, as opposed to one, as the object of research. This perspective reasons that coherent decision-making needs to consider systems' interconnectedness. LÄS MER

4. 3. Integrated Sensing and Communication in Cell-Free Massive MIMO

   Författare :Zinat Behdad; Cicek Cavdar; Ki Won Sung; Özlem Tugfe Demir; Huseyin Arslan; KTH; []
