摘要

在本文中，我们考虑了一个双向中继网络系统，该系统包含多个协作中继，在一个窃听者的参与下在两个信源之间传输信息。为了保证系统的保密性，采用了零空间波束形成方案。我们的目标是在一定的功率传输水平下实现最大的保密和速率。在[1]中，作者提出了一种解决保密和速率最大化(SSRM)问题的方法，而我们使用了另一种基于不同凸函数算法(DCA)的方法。

DC programming and DCA for Secure Guarantee with Null Space Beamforming in Two-Way Relay Networks

In this paper, we consider a two-way relay network system which contains multiple cooperative relays transmitting information between two sources with attendance of an eavesdropper. A null space beamforming scheme is applied to ensure the secrecy in system. Our goal is achieving maximal secrecy sum rate with a certain level power transmit. In [1], authors propose an approach to solve Secrecy Sum Rate Maximization (SSRM) problem, whereas we use another approach based on Different of Convex Functions Algorithm (DCA).
