… But [7] uses orthogonal pilots and its pilot overhead is very large. We propose a channel
estimator that does not require knowledge of inter-cell large-scale fading coefficients, thus no …

… and practical channel estimator for multipath multi-cell massive MIMO TDD systems with
pilot contamination, which poses significant challenges to channel estimation. The proposed …

… proposes a channel-estimation scheme that … channel estimation with comprehensive
knowledge of large-scale fading obtained from pilot reuse sequences is proposed to eliminate pilot …

… -cell layout and ignore the existence of pilot contamination while it is quite often … pilot
contamination in TDDbased massive MIMO systems, we propose two kinds of channel estimation …

… the effect of pilot contamination (PC) on channel estimation. In this paper, analytical
expressions on the mean square error (MSE) of two classical channel estimation algorithms in the …

… the effect of pilot contamination on channel estimation. In turn, … channel estimation and
