摘要：
A simple suboptimal power allocation method is proposed for SC-FDMA systems It is known that the performance of constant power-based allocation methods is close to that of optimal solutions In this letter. by utilizing the waterfilling condition inequality derived for SC-FDMA systems. a threshold is set to select subcarriers for loading constant power to these selected subcarriers It otters competitive performance as confirmed by the simulation results.
