We study how the nonlinearity of the high power amplifier (HPA) affects multi-tone simultaneous wireless information and power transfer (SWIPT). Considering the nonlinear HPA model, we analyze the symbol-error rate performance of the peak-to-average power ratio (PAPR) modulation for the multi-tone SWIPT. Numerical results demonstrate that the HPA has a significant impact on both energy harvesting and information decoding while providing insights which is important to take into account the nonlinearity of the HPA when evaluating the end-to-end efficiency of the multi-tone SWIPT.

多音SWIPT上的功率放大器非线性性能分析

我们研究了高功率放大器（HPA）的非线性如何影响多音频同时无线信息和功率传输（SWIPT）。考虑非线性HPA模型，我们分析了多音频SWIPT的峰均功率比（PAPR）调制的符号误码率性能。数值结果表明，HPA对能量收集和信息解码均具有重大影响，同时提供了见解，这对于评估多音SWIPT的端到端效率时考虑到HPA的非线性非常重要。
