An Overview of Pilot Decontamination Methods in TDD Massive MIMO Systems

Sajjad Ali, Zhe Chen, and Fuliang Yin
Abstract—The fundamental premises of massive multiple-input multiple-output (MIMO) communication systems are to deploy antenna arrays with a few hundred antennas at each base station and to serve a much smaller number of single-antenna terminals using multi-user MIMO transmission. Massive MIMO is an enabler for the development of future broadband wireless networks that scales up the advantages of MIMO by orders of magnitude. While massive MIMO renders many implementation issues, linked to channel estimation, detection and precoding schemes. This paper focuses on the impact of pilot contamination on massive MIMO systems caused by the use of non-orthogonal pilot sequences by the users in adjacent cells and presents an overview of the pilot contamination concept and contemporary research on the issue.

Index Terms—Massive MIMO, multi-user MIMO, pilot contamination, precoding.
