20466 引入等量分解技术，将Gyrator频谱分割为两个分量，并设置不同的阶数，形成两个差异螺旋相位掩码； The Gyrator spectrum is divided into two components by introducing the equivalent decomposition technique, and two differential spiral phase masks are obtained by setting up different orders.
20467 利用奇异值分解(SVD)方法，将其中一个Gyrator频谱分量进行处理，并联合两个差异螺旋相位掩码，分别对其相应的正交矩阵进行编码； Then, the Singular Value Decomposition (SVD) is introduced to process one of theGyrator spectral components so that its corresponding orthogonal matrix is encoded by combining twodifferential phase masks.
20468 最后，通过组合编码后的正交矩阵与对角矩阵，基于可逆SVD技术，输出加密密文。 Finally, by combining the encoded orthogonal matrix and diagonal matrix, the encrypted cipher is outputted based on the reversible SVD technology.

20471 为解决多层异构网(HetNet)中全双工小小区基站(SBS)的回程问题，该文提出一种基于非正交多址接入(NOMA)技术的带内无线回程方案。 To establish effective backhaul connection in multi-tiers Heterogeneous Network (HetNet), by exploiting advanced Non-Orthogonal Multiple Access (NOMA) a novel in-band wireless backhaul scheme is proposed at full-duplex Small cell Base Stations (SBSs).
20472 首先构造出由大规模多输入多输出(MIMO)宏小区基站(MBS)和K层单天线SBS组成的K+1层HetNet，网络中所有基站均工作在全双工模式。 Firstly, a K+1 HetNet is investigated, where the firsttier consists of Macro Base Stations (MBSs) that are equipped with massive MIMO antennas and theremainder K tiers consist of the different types of single-antenna SBSs. The base stations of the whole networkoperate in full-duplex mode.
20473 特别考虑了MBS下行传输模式，允许全双工SBS采用先进的NOMA技术在下行链路移动用户信号上叠加回程信号。 Specially, the downlink transmission of MBSs is considered. Hence, at each SBSthe backhaul signal is superposed over the downlink signal.
20474 接着利用随机几何知识和齐次泊松点过程模型，在此HetNet模型上研究移动用户的小小区上行和回程传输信干比覆盖概率，并讨论SBS的吞吐量。 Then, by using the method from stochastic geometry and modeling all network’s elements as independent homogeneous Poisson Point Processes (PPPs) in this HetNet model, the coverage probabilities of up access link and backhaul link of SBSs are investigated as well as the throughput of small cells.
