Due to the rapid growth of IoT and other connected devices, developing battery-less and/or self-sustainable devices to enable green communication is crucial. This letter presents a practical simultaneous wireless information and power transfer (SWIPT) scheme based on an M-ary quadrature-amplitude modulation (QAM) modulation based technique (M S). The proposed scheme employs hybrid constellation shaping system (HCS) to improve the spectral efficiency. We compare MS with the traditional power splitting scheme based SWIPT (P S) technique. We demonstrate that our proposed scheme outperforms P S in terms of the error rate performance. MS scheme is mainly focused on improving the reliability of low powered IoT sensors and it offers better achievable information rate at operating SNR region as compared to that of P S. Those improvements come at the expense of a slight reduction in the maximum achievable spectral efficiency.
