IMS 2014: MIMO and Beamforming Solutions for 5G Technology

With the possibility of 5G cellular systems being deployed in the cm-wave (3-20 GHz) and mm-wave (30-100 GHz) bands, the unique challenges of those bands have prompted a revisiting of the design and performance tradeoffs associated with existing MIMO techniques. We discuss key implementation issues surrounding the deployment of transmit MIMO processing for 5G systems with a focus on the performance of several basic approaches for multi-user-MIMO (MU-MIMO) transmission.
