Clustered Cell-Free Multi-User Multiple-Antenna Systems with Rate-Splitting: Precoder Design and Power Allocation

In this paper, we address two crucial challenges in the design of cell-free (CF) systems: degradation in the performance of CF systems by imperfect channel state information at the transmitter (CSIT) and high computational/signaling loads arising from the increasing number of distributed antennas an...
