23796 考虑一个存在多窃听者的多小区下行链路蜂窝网络，协作小区通过在选定的子载波上执行协作波束赋形，利用小区间干扰抑制窃听者，实现安全传输。 This paper studies physical layer security of the multi-cell cellular networks, where the base stations need to perform cooperation beamforming in selected subcarriers to secure the downlink communication, and eavesdroppers with random location are interfered by inter-cell interference.
23797 在窃听者位置未知的情况下，推导了下行链路保密连接概率的闭式表达式。 Firstly, the approximation for the secrecy connection probability with uncertained locations of eavesdroppers is obtained.
23798 在此基础上，将下行链路建模为博弈参与者，该文提出一种基于联盟博弈的多小区下行链路保密协作算法，以保密连接概率为效用函数，通过设计联盟加入和退出规则，实现了下行链路对子载波的高效选择和保密协作联盟的自组织生成。 Then a distributed coalition game based cooperation algorithm is proposed to maximize the secrecy connection probability of downlinks. Specifically, the downlink is modeled as game player, whose payoff is the secrecy connection probability in the selected coalition, the join and quit rules of coalitions are designed to make downlinks self-organizing form cooperative coalition and achieve the effective subcarrier allocation.
23799 理论和仿真分析表明所提算法能够形成稳定的联盟结构，并且所提算法的保密性能优于传统的联盟协作算法。 Theoretical analysis and simulation results show that the proposed algorithm can form a stable coalitional structure and results in a notable secure performance advantage relative to the traditional cooperation algorithms.
23800 利用地基观测相机拍摄的以深空为背景的星图受星空复杂背景的影响，往往具有较高的噪声水平。 The star maps acquired by the ground-based cameras are susceptible to the complex background of the starry sky and thus have high noise levels.
23801 同时由于星图目标和噪声呈现较大的相似性，传统的图像去噪算法并不适用于星图。 In addition, the targets in star maps are similar to the noises due to their punctate shapes. As a result, the traditional image denoising method is not applicable to star maps.
23802 为此，该文提出一种基于能量函数的极值中值滤波去噪算法，该算法在去除星图椒盐噪声的同时能够较好地保持图像目标信息。 A new adaptive extremum median filtering denoising algorithm is put forward based on energy function, which can effectively remove the salt and pepper noise of the star maps and keep the small target information at the same time.
23803 该方法针对疑似噪声点采用二次检测的方式，并且结合改进的自适应中值滤波和能量函数模型进行灰度值恢复。 This method employs a twice-check strategy to reduce the false detection ratio of noisy pixels and uses the improved adaptive median filter and the energy function model to recovery noise imagery.
23804 该文分别使用仿真试验和真实星图处理试验对该方法进行验证，在客观评价中，图像峰值信噪比 PSNR(Peak Signal to Noise Ratio)最高可提高 3 倍多，均方误差 MSE(Mean Squared Error)减小为加噪图像的53.1610−×。 The simulated and real star map experiments show that, the Peak Signal to Noise Ratio (PSNR) is improved about 3 times and the Mean Squared Error (MSE) is reduced by 53.1610−× in the terms of objective evaluations.
