dc.description.abstractIn this paper, we propose a three-dimensional (3-D)
channel estimation (CE) scheme to reduce the mean square error
(MSE) in multi-antenna orthogonal frequency division
multiplexing (OFDM) systems. Exploiting the channel correlation
in the spatial domain as well as in the frequency and time domain,
the proposed 3-D CE scheme can outperform conventional twodimensional
(2-D) CE schemes, by either reducing the MSE with
the same complexity or providing the same MSE performance
with less complexity. Simulation results show that the proposed
scheme is quite effective in the presence of spatial correlation.
