Abstract

We consider a simultaneous wireless transfer of information and power in a two-way relaying network, a decode-and-forward protocol and OFDM modulation is employed. Subcarriers are divided into a couple of groups, one is for information decoding, and another is for energy harvesting. With total rate maximized, subcarrier grouping optimization is performed. And the power of subcarriers is optimized according to channel state. The performance of the optimal design is performed on different transmit conditions.

Keywords: SWIPT DF TWR network OFDM subcarrier grouping
