Simultaneous wireless information and power transfer with fixed and adaptive modulation
文献摘要：
Activating Wireless Power Transfer(WPT)in Radio-Frequency(RF)to provide on-demand energy supply to widely deployed Internet of Everything devices is a key to the next-generation energy self-sustainable 6G network.However,Simultaneous Wireless Information and Power Transfer(SWIPT)in the same RF bands is challenging.The majority of previous studies compared SWIPT performance to Gaussian signaling with an infinite alphabet,which is impossible to implement in any realistic communication system.In contrast,we study the SWIPT system in a well-known Nakagami-m wireless fading channel using practical modulation techniques with finite alphabet.The attainable rate-energy-reliability tradeoff and the corresponding rationale are revealed for fixed modulation schemes.Furthermore,an adaptive modulation-based transceiver is provided for further expanding the attainable rate-energy-reliability region based on various SWIPT performances of different modulation schemes.The modulation switching thresholds and transmit power allocation at the SWIPT transmitter and the power splitting ratios at the SWIPT receiver are jointly optimized to maximize the attainable spectrum efficiency of wireless information transfer while satisfying the WPT requirement and the instantaneous and average BER constraints.Numerical results demonstrate the SWIPT performance of various fixed modulation schemes in different fading conditions.The advantage of the adaptive modulation-based SWIPT transceiver is validated.
