Mutual information of amplify-and-forward relaying with partial relay selection
Qiang Xue, Giuseppe Thadeu Freitas de Abreu · 2010
In this paper, we provide asymptotic analysis of the mutual information (MI) of the basic two-hop amplify-and-forward (AF) channel, where the relaying node is selected out of a pool of N potential relay nodes based on instantaneous backward channel state information (CSI). The asymptotic formula obt
