Interference Effect Analysis of Pilot Contaminated Massive MIMO Downlink with Different Pre-coders and Channel Estimation
Abstract: A new idea in cellular MU-MIMO is the use of large numbers of BS antennas to serve several single-antenna terminals simultaneously. In multi-cell environments, adjacent cells using the same spectrum cause a pilot contamination problem and degrade signal quality. This pilot overhead can be reduced by reusing pilot sequences in nearby cells; however, this potentially introduces interference in the channel estimation phase, the so-called "pilot contamination" effect. The achievable rate …
