论文摘要
在这封信中，我们研究了非线性高功率放大器（HPA）对同时无线信息和电力传输（SWIPT）的影响，该影响是点对点多输入多输出通信系统的影响。我们通过考虑HPA非线性及其相关的内存效应来得出速率能量（RE）区域。我们表明，HPA大大降低了可实现的RE区域，并研究了一种预期技术以进行补偿。根据RE区域的增强，评估了建议的预性方案的性能。数值结果表明，对于拆分和分离时间的旋转架构，获得了大约24％的改善。
In this letter, we study the impact of nonlinear high power amplifier (HPA) on simultaneous wireless information and power transfer (SWIPT), for a point-to-point multiple-input multiple-output communication system. We derive the rate-energy (RE) region by taking into account the HPA nonlinearities and its associated memory effects. We show that HPA significantly degrades the achievable RE region, and a predistortion technique is investigated for compensation. The performance of the proposed predistortion scheme is evaluated in terms of RE region enhancement. Numerical results demonstrate that approximately 24% improvement is obtained for both power-splitting and time-splitting SWIPT architectures.
