摘要： 无线携能通信网络中发送端获取用户信道状态信息时,会造成时间和频谱资源的浪费。对此,在多用户多输入单输出网络中研究了发送端只有信道分布信息的节能波束形成设计。在信息中断概率、总可用功率以及授权用户可用功率约束下,网络能量效率通过改进的教与学优化算法实现了最大化。此外,针对提出的功率消耗方案,考虑了非线性能量接收机制并提出功率分流机制,使接收机避免进入饱和区,从而提高了功率接收效率。改进的教与学优化算法结合了鲸鱼优化算法的优点,解决了构造得出的非凸优化问题,并提高了收敛速度。仿真实验分析了动态能量分配场景下中断概率、动态功耗系数以及发送端可用功率对系统能量效率的影响,证实了所提算法的有效性。
