In this paper, we present a novel algorithm for power allocation in the Amplify-and-Forward cooperative communication that minimizes the outage probability with a given value of total power. We present the problem with new formulation and solve the optimal power allocation for a fixed set of partners. The proposed solution provides a direct power allocation scheme with a simple formula that can be also be represented by a simple lookup table which makes it easy for practical implementation. We present simulation results to demonstrate that the performances of the proposed algorithms are very close to results of the previously published iterative optimal power allocation algorithms. We also consider the issue of partner selection in a cooperative network.
