本文研究了多音信号在低射频功率传输和能量采集器中的最佳性能。负载的选择可能很棘手，显示出某种类型的信号优于另一种信号。对于低射频功率（−17dBm），如果为每种情况选择最佳负载，多音信号不会比连续波单音信号提高射频到直流的峰值功率转换效率（PCE），然而，在更高的输出电压（即更大的负载）下，多音信号保持峰值PCE约47%，从而实现更有效的dc到dc电压升压，甚至消除了射频功率接收器中电压升压器的需要。因此，可以将低功率多音波形视为电压灵敏度增强器，而不是PCE效率增强器。这种增强的整流电压是多音信号的关键优势，它可以提高低射频功率接收器的整体效率。
This paper presents a study of the optimal performance of multitone signals in low RF-power transfer and energy harvesters. The choice of the load can be tricky, showing an advantage of a certain type of signals over another. For low RF power (−17dBm), the multitone signals do not improve the peak RF-to-dc power conversion efficiency (PCE) over the continuous wave (CW) single-tone signal, if the optimal load is selected for each case, however, the multitone signals maintain that peak PCE of ∼ 47% over higher output voltage (i.e: larger loads), and consequently enable more efficient dc-to-dc voltage boosting or even eliminate the need for the voltage booster in the RF power receiver. Thus, the low-power multitone waveforms can be considered as a voltage sensitivity booster rather than a PCE efficiency booster. This boosted rectified voltage is the key advantage of the multitone signals that leads to the enhancement in the overall efficiency of the low-RF power receiver.
