Abstract: Power allocation is a key technology in cooperative communication. In this paper, for improving the channel capacity, a multi-nodes and multi-antenna model is proposed for the cooperative communication. Under the assumption of the total power is constant, the improved OPA(Optimum Power Allocation) algorithm is proposed which taking the maximum system capacity as rule. Compared with APA (Average Power Allocation), theoretical analysis and simulation results show that OPA has better performance than APA.

Key words: amplify and forward, system capacity, power allocation
