Multi-sinusoidal waveform shaping for integrated data and energy transfer in aging channels

Abstract

Numerical results demonstrate the advantage of our joint design for the IDET waveform shaping with the existence of the CFO and the outdated CSI. Keywords: integrated data and energy transfer (IDET); wireless energy transfer (WET); simultaneous wireless information and power transfer (SWIPT); carrier-frequency-offset (CFO); waveform; aging channels; outdated channel state information (CSI); orthogonal frequency division multiplexing (OFDM)
