这封信研究了干扰受限无线网络（IWNs）的能量效率（EE）和频谱效率（SE）之间的基本权衡，这是一个非凸优化和NP-难问题。提出了一种嵌入迭代功率分配算法（IPAA）的通用算法过程（GAP），该算法具有收敛速度快、复杂度低、对初值不敏感等优点。仿真结果明确地描绘了IWN的EE-SE权衡曲线。
This letter investigates the fundamental tradeoff between energy efficiency (EE) and spectral efficiency (SE) for interference-limited wireless networks (IWNs), which is a non-convex optimization and NP-hard problem. A general algorithm procedure (GAP) embedded with an iterative power allocation algorithm (IPAA) is proposed, which has good performance with the advantages of fast convergence, low complexity and insensitivity to initial values. Simulation results explicitly depict the EE-SE tradeoff curve for IWNs.
