摘　　要：人工噪声作为一种物理层安全技术,与基于强计算密码学的传统通信安全机制不同,不会被快速发展的算力破解。关于人工噪声辅助多输入多输出(Multi-Input Multi-Output,MIMO)通信系统的安全性的理论研究已相当完备,但由于人工噪声深度依赖即时、准确的信道反馈,其在实际系统中的应用效果仍需通过试验进一步验证。提出了一种人工噪声辅助下的MIMO通信系统仿真实验硬件平台,并通过实验数据证明了人工噪声对合法MIMO通信系统可靠性的影响较小,且能够有效提升系统安全性。As a physical layer security technique,artificial noise is different from conventional cryptography-based communication security mechanisms with high computational complexity,and cannot be cracked by rapidly advancing computing power.Theoretical research on the security of artificial noise-assisted MIMO(Multi-Input Multi-Output)communication systems is quite comprehensive.However,since artificial noise is deeply dependent on the accurate instantaneous channel feedback,its practical application effect still lacks further experiment verification.This paper presents a hardware simulation platform of artificial noise-assisted MIMO communication systems.The experimental results demonstrate that artificial noise can effectively enhance the legitimate MIMO system security with a slight influence on the system reliability.
