提出了一种多用户时分双工（TDD）无线网络中的导频污染攻击（PCA）检测器。我们考虑的情况下，一个积极的窃听者与多个天线尝试PCA的多输入单输出（MISO）目标系统。为了抵御PCA，我们提出了一个PCA检测器，它利用了在双向训练阶段估计的通道之间的不平衡。检测器的性能进行了分析的检测概率。数值计算也进行了各种组合的系统参数，以验证分析结果。
This work presents a detector for a pilot contamination attack (PCA) in multi-user time-division duplex (TDD) wireless networks. We consider a scenario in which an active eavesdropper with multiple antennas attempts a PCA to a Multiple-Input-Single-Output (MISO) target system. To fend off the PCA, we propose a PCA detector which exploits an imbalance between estimated channels in two-way training phases. Performance of the detector is analyzed in terms of detection probability. Numerical evaluations are also conducted for various combinations of system parameters to verify the analytic results.
