Abstract: A transmitting method and receiving method for simultaneous information and energy transfer comprises: determining a first pre-allocated parameter set of a first baseband signal based on a first optimized parameter set and according to a first optimized target and a first constraint condition set; determining a second pre-allocated parameter set of a second baseband signal based on a first optimized result and a second optimized parameter set and according to a second optimized target and a second constraint condition set; and processing the baseband signals into corresponding radio-frequency signals according to the first pre-allocated parameter set and the second pre-allocated parameter set and transmitting the radio-frequency signals through an antenna; the first baseband signal and the second baseband signal each being an information baseband signal or an energy baseband signal. Both the energy transfer efficiency and the information transfer rate are improved by optimizing the information signals and energy signals.

Abstract: A simultaneous information and energy transfer method and system with a guard interval signal are provided. The method comprises the steps of generating, by a transmitting terminal, a controllable guard interval signal according to the current energy demand and environment conditions for channel transmission. The system comprises a transmitting terminal configured to generate a controllable guard interval signal. In the system and method, the guard interval time is fully utilized to transfer a guard interval signal with controllable amount of energy, which not only prevents intersymbol interference, but also provides controllable energy signals within the guard interval time at the same time, thus improving the energy transfer performance of the system and reducing the probability that the receiving terminal is unable to operate normally due to energy shortage. The present invention can be widely applied to a variety of simultaneous wireless information and energy transfer systems.
