Cell-free Massive mimo
FRONTHAUL LINK IN CELL-FREE MASSIVE MIMO In cellular networks, the fronthaul link refers to the connection between the centralized processing unit and the distributed radio units in the network. It carries the digitized baseband signals, control information, and synchronization signals between these components. Cell-free massive MIMO is an advanced wireless communication technique that combines massive multiple-input-multiple-output (MIMO) technology with cell-free network architecture. In cell-free massive MIMO, multiple access points (APs) are deployed throughout the coverage area, and each AP has a large number of antennas. In the context of cell-free massive MIMO, the fronthaul link plays a crucial role in exchanging information between the central processing unit (CPU) and the distributed APs. The CPU performs centralized processing tasks such as channel estimation, beamforming, and resource allocation, while the distributed APs handle the radio transmission and reception. Th...
