Title
A Novel OFDM Power Based Estimation for Dynamic Channel Tracking in Downlink LTE
Abstract
In this paper we compare and test several channel estimation algorithms in the case of LTE (Long Term Evolution) Systems applied in a high mobility environment. In particular, we propose a novel algorithm, based on the observation of OFDM block energy, to perform a semi-blind tracking of the channel between pilot blocks. This algorithm is compared to more traditional approach based on 1D estimation and interpolation. In addition, an Expectation Maximization (EM) is used to improve the overall channel estimation.
