Unification of Frequency direction Pilot-symbol Aided Channel Estimation (PACE) for OFDM

Abstract

Frequency direction Pilot-symbol Aided Channel Estimation (PACE) for Orthogonal Frequency Division Multiplexing
(OFDM) is crucial in high-rate wireless systems. The choice of an estimator for upcoming standards, such as the
Long Term Evolution (LTE) of UTRA, has to take into account their specificities, namely the presence of virtual subcarriers and non-sample-spaced channels. To ease this choice, we propose a unified presentation of estimators encompassing most of the algorithms that can be found in literature, which only differ by the assumptions made on the channel. This unification leads to common Mean Squared Error (MSE) expression, both for sample-spaced and non sample-spaced channels, and enables easy, yet comprehensive comparisons between the estimators.
