摘要：
A new power allocation method was proposed to overcome the drawback of existing methods, which did not take the realistic channel state into consideration, in cooperative communication systems. Based on the system model in B3G/4G cooperative communication, the new method presents the definition of MCPA (Mean Channel Power Allocation), and accordingly sets the selection threshold for cooperative nodes. The simulation results show that, compared to those existing power allocation methods such as equal allocation to all nodes and equal allocation to selected nodes with threshold based on outage probability, the new method exhibits better performance in various kinds of channel condition, which is more pronounced in the situation of bad channel condition.
