摘要：

Energy-efficient transmission is a hot topic in wireless communication due to the conflict between the booming traffic demand and the limited energy resource. In this paper, an algorithm for downlink power allocation combined with user association is studied to improve the energy efficiency of a software defined cellular network. The problem mentioned above is non- convex but can be solved with QPSO, a low-complexity and high-efficiency algorithm. Our new proposed algorithm optimizes the energy efficiency while maximum power constraints and minimum rate constrains are assured. Simulation result shows the system energy efficiency precede to that of previous algorithm, when the proposed scheme is applied.
