Exploiting second order statistics of the received signals in AF relay cooperative network for compound channel estimation

Author	Kanjirathumkal, Cibile K. Sameer, S. M. Jacob, Lillykutty
Abstract	In this paper we address the channel estimation issue in amplify and forward (AF) relay network by exploiting the temporal statistics of the fading channel. A robust channel estimator that offers good performance is proposed for dual hop AF systems which can be used with any type of correlated channels. The linear minimum mean square error (LMMSE) estimation technique used in existing methods require apriori knowledge of exact autocorrelation function (ACF) of the channel at the receiver. Time domain channel correlation mismatch can degrade the performance of LMMSE estimator. The proposed method offers a realistic solution as the interpolation factor is extracted from the received signal itself. Since it can accommodate the temporal variations of the channel effectively, this method offers flexibility in estimating any generalised correlated channels. The mean square error (MSE) and bit error rate (BER) performance of the proposed technique are evaluated through computer simulation studies and are compared with that of a related method referred in the literature. The improvement in the system performance owes to the enhanced correlation matching.
