In this paper, a novel N-tone multitone amplitude shift keying (ASK) transmission signal scheme is proposed by utilizing the non-linearity of integrated information-energy rectifier receiver architecture. The data rate is increased by transmitting (N-1) symbols over a single N-tone Multitone ASK signal stream. Wireless power transfer (WPT) and wireless information transfer (WIT) performances of the proposed transmission scheme are analyzed, and a trade-off between WPT and WIT performances is discussed. WPT performance of the designed transmitted signal has been shown to improve with increasing the minimum level of the symbols approaching the maximum possible power efficiency of the rectifier. Logarithmically distributed symbols have been shown to improve WPT compared to linearly distributed symbols due to the non-linearity of the rectifier circuitry, whereas linearly distributed symbols result in better WIT performance. It is possible to attain a good WIT performance with a low transmitted signal power.

Abstract:

In the era of Internet of Things (IoT) networks, far-field wireless power transfer using radio frequency (RF) waves has attracted attention as a solution to remove the need for batteries at the sensors. However, RF communication signals can be used for energy as well as information for better resource management. Therefore, recently, simultaneous wireless information and power transfer (SWIPT) technology has gained significance for charging these low-power IoT devices wirelessly. In this paper, a novel N-tone multitone amplitude shift keying (ASK) transmission signal scheme is proposed by utilizing the non-linearity of integrated information-energy rectifier receiver architecture. The data rate is increased by transmitting (N-1) symbols over a single N-tone Multitone ASK signal stream. Wireless power transfer (WPT) and wireless information transfer (WIT) performances of the proposed transmission scheme are analyzed, and a trade-off between WPT and WIT performances is discussed. WPT performance of the designed transmitted signal has been shown to improve with increasing the minimum level of the symbols approaching the maximum possible power efficiency of the rectifier. Logarithmically distributed symbols have been shown to improve WPT compared to linearly distributed symbols due to the non-linearity of the rectifier circuitry, whereas linearly distributed symbols result in better WIT performance. It is possible to attain a good WIT performance with a low transmitted signal power.
