Cloud radio access networks (C-RANs) emerge as appealing
architectures for next-generation wireless/cellular systems
whereby the processing/decoding is migrated from the local
base-stations/radio units (RU) to a control/central units (CU)
in the "cloud".
This is facilitated by fronthaul links connecting the RUs
to the managing CUs. We focus on oblivious processing at the
RU, and hence the fronthaul links carry digital information about the baseband
signals, in the uplink from the RUs to the CU and vice versa in the
downlink. The high data rate service demands in C-RANs, imply
that even with fast (optical) fronthauls, let alone for heterogeneous
fronhauls, efficient compression of the basedand signals is essential.
In this talk we focus on advanced robust signal processing solutions,
emerging by network information theoretic concepts, and review
also the basic approaches to this cloud network.
Multi-hop fronthaul topologies are also discussed.
Analysis and numerical results illustrate the considerable
performance gains to be expected for different cellular models.
Some interesting theoretical directions conclude the presentation.
