This study evaluates the performance of large intelligent surface (LIS) technology in the context of a multi-user MIMO mobile communication system (Mu-MIMO) proposed for the sixth generation (6G). LIS employs digitally controlled reflectors to enhance Signal-to-Interference plus Noise Ratio (SINR) and establish line of sight (LoS) connectivity in non-LoS environments, improving transmission security. Analytical expressions are derived to assess LIS performance metrics, including distribution parameters, bit error probability, and secrecy outage probability, considering the presence of eavesdroppers and environmental fading. The study highlights the potential of LIS technology to enhance the confidentiality and reliability of digital communication systems in next-generation networks.
本研究评估了大型智能表面（LIS）技术在为第六代（6G）提出的多用户多输入多输出（Mu-MIMO）移动通信系统背景下的性能。LIS采用数字控制反射器来提高信号与干扰加噪声比（SINR），并在非视距（LoS）环境中建立视距连接，从而提高传输安全性。推导了分析表达式，以评估LIS的性能指标，包括分布参数、误码率和保密中断概率，同时考虑了窃听者的存在和环境衰落。该研究突出了LIS技术在增强下一代网络中数字通信系统的保密性和可靠性方面的潜力。
