In this paper, we present channel estimators for
Long Term Evolution Advanced (LTE-A) fast fading channels.
We show that the LTE-A Reference Signals (RS) structure-
despite being designed for rather static scenarios-allows for
accurate estimation performance even for higher speeds. We
derive a Linear Minimum Mean Square Error (LMMSE) estima-
tor and outline the restrictions that the LTE-A standard places
on this estimator. Moreover, we present a novel Least Squares
(LS) estimator based on a smoothness constraint, attempting
to approach the performance of the LMMSE estimator, as our
simulations reveal the rather limited capabilities of conventional
interpolation techniques.
