Time Varying Channel Estimation for Amplify-and-Forward Relay Network

Time Varying Channel Estimation for Amplify-and-Forward Relay Network

For high Doppler spread channel scenario, in this paper, we develop a channel estimation method for Orthogonal Frequency Division Multiple Access (OFDMA) based Amplifyand-Forward (AF) relay network. Specifically, using Basis Expansion Model (BEM) the fast time varying channels in Source-Relay a...
