我们研究了第五代(5G)及以后网络中具有非理想硬件的大规模多输入多输出(MIMO)系统中的发射机认证。提出了一种新的基于信道的认证方案。基于信号处理理论,首先推导出硬件损伤下的信道估计公式,确定误差协方差矩阵,评估硬件损伤对认证性能的影响。借助于假设检验和矩阵变换理论,我们能够推导出在不同信道协方差矩阵模型下虚警概率和检测概率的精确表达式。大量的仿真验证了理论结果,并说明了所提出的方案的效率。系统参数对性能的影响,以及揭示。
We study transmitter authentication in massive multiple-input multiple-output (MIMO) systems with non-ideal hardware for the fifth generation (5G) and beyond networks. A new channel-based authentication scheme is proposed by taking hardware impairments into account. Based on signal processing theory, we first formulate channel estimation under hardware impairments and determine error covariance matrix to assess the quantity caused by hardware impairments on authentication performance. With the help of hypothesis testing and matrix transformation theories, we are then able to derive exact expressions for the probabilities of false alarm and detection under different channel covariance matrix models. Extensive simulations are carried out to validate theoretical results and illustrate the efficiency of the proposed scheme. Impacts of system parameters on performance are revealed as well.
