Abstract
A more efficient 5G network can be achieved by leveraging a centralized radio access network (CRAN) and/or a virtualized radio access network (VRAN) architecture to comply with transport bandwidth requirements for better performance. Additionally, linear compression techniques can be used to reduce the transport bandwidth. Compression on a fronthaul can be achieved by utilizing the concept of spatial compression. After a signal has been compressed, it can be decompressed in accordance with a number of antennas.
