In order to increase capacity and reduce power consumption for future cellular
networks, new cellular architectures and radio access schemes will be required. Two important
technologies for future 5G networks include Cloud-Radio Access Networks (C-RAN) [1] and Large Scale
Antenna Systems (LSAS) with hundred's of low power radios to increase the cell capacity with multi-user
MIMO multiplexing and beamforming. Although LSAS in theory [2] promises large capacity gains at the
fraction of the power consumed by the current macro-basestations; there are many practical challenges
that need to be overcome before LSAS can be successfully integrated into current and future cellular
networks including: 1) low-power beamforming algorithms and 2) irregular array beamforming. This
project examines each challenge and proposes possible solutions.
