提出了一种降低多载波调制系统峰均功率比的新方法。将降阶问题转化为组合优化问题，并采用Hopfield神经网络（HNN）进行求解，该网络结构简单，适合于实时优化。仿真结果表明，HNN比所选择的映射方法更有效。
A novel method for the reduction of the peak-to-average power ratio of multicarrier modulation systems is proposed. The reduction problem is rewritten to a combinatorial optimisation and is solved using the Hopfield neural network (HNN), which has a simple structure and is suitable for real-time optimisation. Simulation results show that the HNN is more effective than the selected mapping method.
