In this paper, we address the challenging issue of multi-hop cooperative relaying over heterogeneous compound channels, where constituent channels can incorporate topographical variations and respective distribution changes (due to environmental factors). Existing methods in the literature address various issues pertinent to receiver design by assuming a(More)
Analytical approaches for the characterisation of the compound channels in transparent multihop relay transmissions over independent fading channels are considered in this paper. Compound channels with homogeneous links are considered first. Using Mellin transform technique, exact expressions are derived for the moments of cascaded Weibull distributions.(More)
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)(More)
