MIMO Cooperative Multiple-Relay Networks With OSTBCs Over Nakagami-M Fading
In this paper, the performance of a dual-hop Multiple-Input Multiple-Output (MIMO) cooperative multiple-relay network using Orthogonal Space-Time Block Coding (OSTBC) transmission is examined. The fading environment is modeled as independent, not identical distributed (i.n.i.d.) Nakagami-m fading. Also, the authors consider the case that each terminal in the network has multiple-antennas, the relays operate in Channel State Information (CSI)-assisted Amplify-and-Forward (AF) relaying mode, and the direct transmission from the source to the destination is applicable. In particular, they derive a closed-form expression for the Moment Generating Function (MGF) of the instantaneous Signal-to-Noise Ratio (SNR).
