DFT-based Channel Estimation Techniques for Massive MIMO Systems
2018 25th International Conference on Telecommunications (ICT)
In massive MIMO systems, efficient and highly accurate channel state information (CSI) at the base station are essential requirements for tackling the effect of pilot contamination to achieve the potential benefits of the systems. In this paper, we propose two discrete Fourier transform (DFT)-based channel estimation techniques for massive MIMO systems. The proposed methods mitigate the pilot contamination significantly via modifying the DFT-based estimation through iterations and mostdoi:10.1109/ict.2018.8464829 dblp:conf/ict/Al-SalihiNL18 fatcat:ej52utvfavch3pwsfio5i7jnna
