Channel estimation accuracy limits the performance of multi-cell millimeter-wave (mm-Wave)massive MIMO systems, because reusing pilots across cells causes pilot contamination and inter-cellinterference (ICI). This paper proposes a low-complexity semi-blind channel estimator based on singular value decomposition (SVD) for multi-cell multi-user mm-Wave
