Abstract

This letter introduces pilot-based codebook artificial noise (PCAN) into movable antenna (MA)-enabled MIMO communication systems. It investigates the problem of optimizing secrecy capacity (SC) through the joint optimization of transmit covariance matrices and antenna positions. The sequential convex programming (SCP) method is employed to linearize the non-convex parts of the optimization problem, and an alternating optimization (AO) algorithm is utilized to iteratively solve for both the transmit covariance matrices and antenna positions. Simulation results demonstrate a significant improvement in SC. The proposed approach provides a robust solution for enhancing physical layer security in wireless communication systems, offering practical insights for future secure communications.

基于导频的MIMO系统物理层安全性增强的码本人工噪声

本文将基于导频的码本人工噪声（PCAN）引入到可移动天线（MA）的MIMO通信系统中。研究了通过联合优化发射协方差矩阵和天线位置来优化保密能力的问题。采用序列凸规划（SCP）方法对优化问题的非凸部分进行线性化，采用交替优化（AO）算法对发射协方差矩阵和天线位置进行迭代求解。仿真结果证明了SC的显著改进。所提出的方法为增强无线通信系统的物理层安全性提供了一个强大的解决方案，为未来的安全通信提供了实用的见解。
