Abstract
Downlink channel estimation in millimeter-wave (mmWave) frequency division duplex (FDD) massive multiple input multiple output (MIMO) systems is investigated in this letter. Considering the sparse scattering nature of the mmWave channels, the estimation problem is formulated as a sparse parameter estimation problem. A low-complexity orthogonal matching pursuit (OMP) estimation algorithm is proposed by exploiting the inherent correlation in the...
