الملخص EN
In this paper, we research synthesis scheme for secure wireless communication in multibeam directional modulation (MBDM) system, which consists of multiple legitimate users (LUs) receiving their own individual confidential messages, respectively, and multiple eavesdroppers (Eves) intercepting confidential messages.
We propose a new type of array antennas, termed frequency diverse arrays (FDA), to enhance security of confidential messages.
Leveraging FDA technology and artificial noise (AN) technology, we aim to address the PHY security problem for MBDM by jointly optimizing the frequency offsets, the precoding matrix and the AN projection matrix.
In the first stage, with known locations of Eves, precoding matrix is designed to minimize Eve’s receiving power of confidential message (Min-ERP), while satisfying power requirement of LUs.
And then artificial-noise projection matrix (ANPM) is calculated to enhance AN impact on Eves without influencing LUs.
Furthermore, we research a more practical scenario, where locations of Eves are unknown.
Unlike the scenario of the known locations of Eves, precoding matrix is designed to maximize AN transmit power (Max-ATP), while satisfying each LU’s requirement received power of confidential message.
In the second stage, we analyze and further optimize secrecy capacity.
The problem is solved by optimizing frequency offsets through modified artificial bee colony (M-ABC) algorithm.
Numerical results show that the proposed scheme can achieve a secure transmission in MBDM system.
