摘要：
This paper proposes a modified decode-and-forward (DAF) protocol with a three-node model, which contains two users and one destination. Each user can be either the source or the relay in different frames. We analyze the four cooperative cases in the first frame and run simulations to obtain the optimal power allocation coefficients in the second frame. The closed-form expression of outage probability is derived over Nakagami-m fading channels. Furthermore, we show that the proposed model has better performance than the non-cooperation system and traditional DAF strategy based on the derived outage probability.
