| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In massive multi-user MIMO (MU-MIMO) systems, the base station (BS) requires accurate channel state information (CSI). In the time division duplex (TDD) system, usually the CSI is estimated by the pilot signal transmitted from users. However, the estimation accuracy of CSI is degraded by the effect of pilot contamination which occurs when the non-orthogonal pilot is reused by users in neighboring cells. In this report, we propose a low-complexity minimum mean squared error (MMSE) channel estimation method for the massive MU-MIMO system to solve the pilot contamination problem. Our proposed method combines the singular value decomposition (SVD) with the traditional MMSE estimation method. The computational complexity is reduced by restricting the dimensions both of the long-term channel covariance matrices and received pilots. The simulation results show that the proposed method outperforms the traditional MMSE estimation method in terms of the normalised mean square error (NMSE) with a large number of antennas at BS. |
