    Abstract: Provided are a SiC/ZrC composite fiber, a preparation method and use thereof. The SiC/ZrC composite fiber has a diameter of 10 to 70 μm. The method includes mixing liquid polycarbosilane with a zirconium-containing polymer to obtain a hybrid spinning solution, and then performing electrospinning to obtain a SiC/ZrC composite fiber precursor, crosslinking and thermally treating the SiC/ZrC composite fiber precursor in a protective atmosphere to obtain the SiC/ZrC composite fiber. The SiC/ZrC composite fiber is continuous and uniform, has an adjustable diameter, and thus has outstanding tensile strength and breaking strength and excellent high-temperature resistance. Without use of any organic solvent or spinning agent, the method achieves short process flow and high yield, indicating wide application prospects.

    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.
