Abstract

In this paper, simultaneous wireless information and power transfer based on time-frequency block allocation (TFBA-SWIPT) is proposed to save the energy of an orthogonal frequency-division multiplex (OFDM) decode-and-forward cooperative communication system, by allocating different resource blocks for information decoding and energy harvesting at the relay and destinations. The joint allocation of time-frequency blocks and power is optimized to maximize the transmission rate of the destination, while ensuring the transmission rate and energy supply of the relay. The time-frequency block pairing algorithm and the block power allocation algorithm are integrated to achieve the optimal solution. Simulation results illustrate the benefits of using TFBA-SWIPT in the OFDM cooperative communication system over time-varying channels.
