摘要：
In this paper, the problem of power allocation in the amplify-and-forward (AF) cooperative network is investigated based on the achievable maximum signal-to-noise ratio at the destination node. With assumptions that the source node has the perfect channel state information, optimal power allocation algorithms are developed for the relay networks under two scenarios: the full cooperative scheme with direct transmission (DT) from source node to destination node and relay cooperative scheme without DT. With the proposed optimal power allocation algorithm, simulation results demonstrate that the performance of AF relay networks can be significantly improved.
