摘要：【中文】本发明的有益效果为，本发明提供了一种MIMO系统中人工噪声辅助矢量扰动预编码的安全传输方法。本发明通过在发送端采用非线性矢量扰动预编码，以控制发送信号的功率，将发送信号的功率降在相当低的范围内，除此之外，由于在窃听方知道合法方的信道信息后，传统的多输入多输出系统无法保证传输的安全性，为了保证通信传输安全，在发送信号中引入正交于合法方信道矩阵的人工噪声，可以使合法方的信息不受人工噪声的影响，然而窃听方将会受到严重的影响，导致窃听方的BER很高。最终根据合法方和窃听方的SINR可以看出，在引入人工噪声的非线性预编码多输入多输出系统中，合法方的SINR高于窃听方的SINR。 【EN】The invention has the beneficial effect that the invention provides a safe transmission method for the artificial noise auxiliary vector disturbance precoding in the MIMO system.

Finally, according to the SINRs of the legal party and the eavesdropper, in the nonlinear precoding multiple-input multiple-output system introducing artificial noise, the SINR of the legal party is higher than that of the eavesdropper.
