Location-aided pilot contamination elimination for massive MIMO systems
2016 (English)In: 2015 IEEE Global Communications Conference, GLOBECOM 2015, New York: IEEE conference proceedings, 2016Conference paper, Published paper (Other academic)
Abstract [en]

Massive MIMO systems, while being a promising technology for 5G systems, face a number of practical challenges. Among those, pilot contamination stands out as a key bottleneck to design high-capacity beamforming methods. We propose and analyze a location-aided approach to reduce the pilot contamination effect in uplink channel estimation for massive MIMO systems. The proposed method exploits the location of user terminals, scatterers, and base stations. The approach removes the need for direct estimation of large covariance matrices and provides good channel estimation performance in the large antenna regime.
