54378	两个阶段联合导频优化，提高了系统的网络吞吐量。	The two-stage joint pilot optimization improves the network throughput of the system.
54379	仿真结果表明，文中提出的方法性能明显优于目前的研究所提出的分开优化导频分配和导频功率的方法性能。	The simulation results show that the performance of the method proposed in the article is significantly better than the performance of the method of separately optimizing pilot allocation and pilot power proposed by current research.
54380	针对封闭环境下的混响对智能语音处理系统性能的影响，论文提出了一种麦克风阵列语音去混响方法。	In order to avoid the impact of reverberation in enclosed environments on the intelligent speech processing system, an adaptive speech dereverbration method was proposed in this thesis.
54381	考虑到阵列接收信号所构建的协方差矩阵存在部分数值为零，进而造成输出语音信号失真的情况，	Given that some values of the covariance matrix constructed by the speech signal on microphone array might be zero, which may cause distortion of the output speech signal.
54382	论文给出基于两个通道语音信号功率谱的相干扩散功率比(CDR)来实现协方差初始化，采用递归平均得到阵列接收信号协方差矩阵的估计值，进行通过多通道线性预测来优化MCLP的去混响方法。	The speech dereverbration using multi-channel linear prediction(MCLP) were adopted in the thesis, based on double-channel coherent-to-diffuse power ratio(CDR) covariance initialization and employing estimated value of the covariance matrix of the array received signals obtained by recursive averaging.
54383	实验结果表明，通过不同混响条件下不同方法的比较，论文提出的去混响算法均取得了较好的去混响效果。	The experimental results show that the improved MCLP algorithm is more effective by comparing different methods in different reverberation environments.
54384	针对下行双用户NOMA(Non-Orthogonal Multiple Access)系统模型中存在智能窃听者，该窃听者可自适应地选择被动窃听或主动干扰工作模式，	In a downlink non-orthogonal multiple access(NOMA) system model with double users, there exists an intelligent eavesdropper that performs either passive eavesdropping or active jamming adaptively.
54385	在不精确了解其干扰水平的情况下，部分NOMA用户很有可能遭遇传输质量下降乃至保密中断，这将对信息安全传输构成严重威胁。	Without an accurate understanding of the interference level, some NOMA users are likely to experience degraded transmission quality or even confidential interruptions, which threaten the secure transmission severely.
54386	另外，由于信道衰落，用户的位置对系统整体性能有很大影响，难以保证距离源节点较远用户的传输质量。	Besides, the user's location has a great influence on performance due to the open nature of wireless channel, so edge users far away from the source node cannot guarantee the user's information transmission rate.
