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.

用于基于干扰对齐的网络的安全绿色通信方案
在本文中,针对基于干扰对齐(IA)的网络提出了一种新的安全和绿色通信方案。为了实现安全通信,全双工接收器被用来传输人工噪声 (AN)。信号和AN都用于收集能量以实现绿色通信。为此,首先分析了该方案的可行条件。其次,研究了平均传输速率、保密性能和收集的能量。第三,给出了同时无线信息和功率传输(SWIPT)的优化方案,以优化信息传输和能量收集效率。同时,设计了一种改进的IA迭代算法来消除AN和干扰。此外,考虑中继协作,分析其系统性能。仿真表明,目标平均传输速率不受AN的影响,保密性能可以得到很大的提高。能量收集效率也优于传统方案。正如预期的那样,通过中继协作进一步提高了平均传输速率。
