| Abstract: | To solve the problem of power allocation for non-regenerative amplification-and-forwarding relaying communication systems with limited capacity,two power allocation schemes based on optimal capacity rule are proposed,called generous scheme and stingy scheme,respectively.The simulation results have shown that the proposed two power allocation schemes can improve system capacity with different degrees. |

| Keywords: | cooperative communication power allocation capacity limitation |
