In the slow fading channel,the cooperative diversity is a new space diversity.Based on the fact that the power of the channles and noises of the cooperative nodes may be different to the destination node.A new method called jointed power allocation was put forward,which is maximum ratio combining at the destination node and the transmit-maximum ration combining at each transmiter node with water-filling synthetically.The simulations under Gaussian and Rayleigh channel were carried out.The analytical result and simulations showed that the performance can be improved by this method.At the same time,a suboptimal method was put forward to reduce the complexity.
