Elena Boshkovska

摘要:

同时无线信息和功率传输(SWIPT)是实现长寿命和自我可持续的无线网络的有前途的解决方案。在这篇论文中,我们提出了一个实用的非线性能量收集(EH)模型,并设计了SWIPT系统的资源分配算法。特别地,算法设计被公式化为非凸优化问题,用于在EH接收器处的总收获功率的最大化,该EH接收器受到信息解码(ID)接收器的服务质量(QoS)约束。为了避免问题的非凸性,我们将相应的非凸的比率和目标函数转换成一个等价的目标函数的参数减法形式。此外,我们设计了一个计算效率高的迭代资源分配算法,以获得全局最优解。数值结果表明,显着的性能增益的平均总收获功率的建议的非线性EH接收机模型相比,传统的线性模型。

英文摘要:

Simultaneous wireless information and power transfer (SWIPT) is a promising solution for enabling long-life, and self-sustainable wireless networks. In this thesis, we propose a practical non-linear energy harvesting (EH) model and design a resource allocation algorithm for SWIPT systems. In particular, the algorithm design is formulated as a non-convex optimization problem for the maximization of the total harvested power at the EH receivers subject to quality of service (QoS) constraints for the information decoding (ID) receivers. To circumvent the non-convexity of the problem, we transform the corresponding non-convex sum-of-ratios objective function into an equivalent objective function in parametric subtractive form. Furthermore, we design a computationally efficient iterative resource allocation algorithm to obtain the globally optimal solution. Numerical results illustrate significant performance gain in terms of average total harvested power for the proposed non-linear EH receiver model, when compared to the traditional linear model.\
