Backhaul-Constrained Multicell Cooperation Leveraging Sparsity and Spectral Clustering
Backhaul-Constrained Multicell Cooperation Leveraging Sparsity and Spectral Clustering
Multicell cooperative processing with limited backhaul traffic is studied for cellular uplinks. Aiming at reduced backhaul overhead, a sparse multicell linear receive-filter design problem is formulated. Both unstructured distributed cooperation and clustered cooperation, in which base station groups are formed for tight cooperation, are considered. Dynamic clustered cooperation, where the …
