    • Secure resource allocation against colluding eavesdropping in a user-centric cell-free massive multiple-input multiple-output system

    • 以用户为中心的去蜂窝大规模多输入多输出系统中抗协作窃听的安全资源分配
    • “无线通信技术领域迎来重要突破。针对多被动窃听者勾结情况下的无蜂窝大规模多输入多输出（MIMO）系统的资源分配问题，专家提出了一种新的解决方案。该研究旨在解决有限导频资源问题，通过接入点（AP）选择和导频传输功率优化，为用户分配最小导频污染的导频，以提高信道估计的准确性。同时，面对多个被动窃听者勾结环境下的安全传输问题，该研究基于局部部分迫零预编码方案，制定了传输功率优化策略，旨在最大化系统的最小安全频谱效率。仿真结果表明，该方案能有效降低信道估计误差，提升系统安全性。这一研究为无线通信领域的资源分配和安全传输问题提供了新的解决思路，具有重要的理论和实践意义。”
