Five Disruptive Technology Directions for 5G
Federico Boccardi, Robert W. Heath, Angel Lozano +2
New research directions will lead to fundamental changes in the design of future 5th generation (5G) cellular networks. This paper describes five technologies that could lead to bo…
Massive MU-MIMO Downlink TDD Systems with Linear Precoding and Downlink Pilots
Hien Quoc Ngo, Erik G. Larsson, Thomas L. Marzetta
We consider a massive MU-MIMO downlink time-division duplex system where a base station (BS) equipped with many antennas serves several single-antenna users in the same time-freque…
Massive MIMO for Next Generation Wireless Systems
Erik G. Larsson, Ove Edfors, Fredrik Tufvesson +1
Multi-user Multiple-Input Multiple-Output (MIMO) offers big advantages over conventional point-to-point MIMO: it works with cheap single-antenna terminals, a rich scattering enviro…
