Abstract
In this paper we present approximations of the outage probability for an amplify-and-forward MIMO relaying system with three nodes, which employs multiple antennas at the nodes and orthogonal space-time block coding (OSTBC) transmission over a flat Rayleigh fading. In the amplify-and-forward relay, the incoming signal is decoupled, amplified and forwarded to the destination. Under assumption of availability of full channel state information at the relay and destination and availability of direct link between the source and destination we derived expression for approximation of the outage probability which is sufficiently accurate in the entire SNR range of practical interest. The results obtained by this approximation are compared with the approximations for outage probability of the system without direct link to the destination.
