本文提出了一种用于多输入单输出单天线窃听（MISOSE）衰落信道下保密通信的极化编码方案。我们考虑的情况下，块衰落信道与已知的窃听信道状态信息（CSI）和衰落信道与已知的窃听信道分布信息（CDI）的情况。我们使用人工噪声辅助的安全预编码方法，以最大限度地提高保密容量在第一种情况下，并克服不知道窃听CSI在第二种情况下。我们表明，我们提出的方案可以提供可靠和安全的通信MISOSE信道的编码和解码复杂度低。
In this paper, we propose a polar coding scheme for secure communication over the multiple-input, single-output, single-antenna eavesdropper (MISOSE) fading channel. We consider the case of block fading channels with known eavesdropper channel state information (CSI) and the case of fading channels with known eavesdropper channel distribution information (CDI). We use the artificial noise assisted secure precoding method to maximize the secrecy capacity in the first case, and to overcome the unawareness of the eavesdropper CSI in the second case. We show that our proposed scheme can provide both reliable and secure communication over the MISOSE channel with low encoding and decoding complexity.
