Argos: Realizing Massive-MIMO

The capacity of traditional singleuser wireless systems is exclusively limited by the available spectrum and transmission power. Recent developments in information theory, however, have shown that such capacity limitations can be overcome by improving the spatial reuse efficiency through multiuser multipleinput multipleoutput (MUMIMO) technology, or its special form called multiuser beamforming (MUBF). In the Argos project we develop new techniques that enable hundreds of antennas to be deployed on base stations, resulting in enormous network capacity gains. We use the WARP platform to build the first realworld prototypes of a manyantenna MUBF base station and experimentally evaluate its performance. Our research demonstrates the feasibility of manyantenna base stations, and is designed to motivate industry adoption of this promising technology in the near future.
