摘要翻译：
本文比较了不同的线性和非线性射频能量收集模型，包括有限灵敏度和无限灵敏度，用于同时进行无线信息和功率传输(SWIPT)。在一系列RF采集模型下，成功的SWIPT接收的概率被严格量化，使用了商业RFID背景下最先进的整流器。SWIPT文献的很大一部分使用了过于简化的模型，没有考虑到潜在采集电路的有限灵敏度或非线性。研究表明，通信信号并不总是适合于同时进行能量传递，并得出结论：在实际的SWIPT研究中，应仔细考虑收割机固有的非理想特性；并给出了具体的收割机建模方法。

英文摘要：
This work compares different linear and nonlinear RF energy harvesting models, including limited or unlimited sensitivity, for simultaneous wireless information and power transfer (SWIPT). The probability of successful SWIPT reception under a family of RF harvesting models is rigorously quantified, using state-of-the-art rectifiers in the context of commercial RFIDs. A significant portion of SWIPT literature uses oversimplified models that do not account for limited sensitivity or nonlinearity of the underlying harvesting circuitry. This work demonstrates that communications signals are not always appropriate for simultaneous energy transfer and concludes that for practical SWIPT studies, the inherent non-ideal characteristics of the harvester should be carefully taken into account; specific harvester's modeling methodology is also offered.
