针对单发单收系统下传统人工噪声失效的问题，提出基于合法方信道状态信息生成导频域人工噪声，将发送的导频信息隐蔽在人工噪声下，保证窃听方无法获取信道状态信息从而无法解调。合法方采用正交匹配追踪算法(OMP)进行信道估计从而完成信息解调。仿真证明，该方案在不影响合法方性能的情况下，有效地干扰了窃听方。这一研究成果证实了基于合法方信道状态信息的导频人工噪声方案的安全性。
Abstract：Regarding the problem of traditional artificial noise failure in a single-input-single-output system, this paper proposes to generate artificial noise in pilot based on the channel state information of the legitimate party.The transmitted pilot information is concealed under the artificial noise to ensure that the eavesdropping party cannot obtain channel state information and thus cannot demodulate.Orthogonal matching pursuit(OMP) algorithms are used to estimate channels and perform information demodulation.Simulation results show that the scheme can effectively interfere with the eavesdropper without affecting the performance of the legitimate party.This research result proves the safety of artificial noise scheme in pilot based on legitimate channel state information.
