“…Therefore, the concept of wireless powered communication (WPC) was raised [31], [32]. In fact, with the advent of collecting energy methods using radio frequency (RF) signals, WPC have caused extensive research and attention [33]- [42]. In these studies, the authors studied the sustainability analysis of WPC and the relation between interference and energy harvesting in [35]- [37].…”

In this paper, a new security and green communication scheme is proposed to the Interference-Alignment (IA) based networks. To achieve a secured communication, full-duplex receivers are utilized to transmit artificial noise (AN). Both the signals and the ANs are used to harvest energy to realize green communication. For these reasons, the feasible conditions of this scheme are analyzed first. Secondly, the average transmission rate, the secrecy performance and the harvested energy are investigated. Thirdly, an optimization scheme of simultaneous wireless information and power transfer (SWIPT) is given to optimize the information transmission and the energy harvesting efficiency. Meanwhile, an improved IA iteration algorithm is designed to eliminate both the AN and the interference. Furthermore, relay cooperation is considered and its system performance is analyzed. The simulations show that the target average transmission rate is not affected by AN, while the secrecy performance can be greatly improved. The energy harvesting efficiency is also better than the traditional schemes. As expected, the average transmission rate further is improved with the relay cooperation.

INTRODUCTION HE broadcast characteristics of the wireless communication networks (WCNs) determine that it is an open communication environment. The sharing of its information medium leads to intricate electromagnetic radiation problems. Of these, multiuser interference, wireless transmission secrecy and radio signal enabled wireless power transfer are intensively discussed in these WCNs [1]-[3].  Interference exists widely in multiuser WCNs, and this affects multiplexing rate of time slots, frequencies, and code space, which severely limits the reusability of channel resources and reduces the spectrum of networks. It has become  Manuscript received April 06, 2019.
