Abstract:In 5G communications, the increasing demand for high data rate and ubiquitous services has led to a large energy consumption in both transmitter and receiver. Wireless power transfer (WPT) has been proposed as an effective energy saving method. However, WPT and wireless information transfer (WIT) are often separated in a communication system. In this paper, a 5G-based green broadband communication system with simultaneous wireless information and power transfer (SWIPT) is proposed to combine WIT and WPT. In the system, the subband sets available for WIT and WPT are defined by two complementary spectrum marker vectors, and two independent frequency domain signals using different subband sets are achieved by calculating the inner product of spectrum marker vector, pseudo-random (PR) phase and power scaling vector. Time domain fundamental modulation waveform (FMW) is generated by doing inverse fast Fourier transform (IFFT) of the frequency domain signal. The data stream is modulated on the FMW for WIT, while the FMW for WPT is transmitted directly. The BER performance of the system is analyzed. A joint optimization unit has been deployed to maximize the system throughput by jointly optimizing subband sets and subband powers subject to the constraints of energy requirement and interference. The simulation results have shown the outstanding performance of the designed system. (C) 2018 Elsevier B.V. All rights reserved.
