6814 仿真表明,该方法不需要先验信息就能够在抑制干扰的同时进行盲波束形成,在OFDM信号来向上获得高增益的主瓣,进而提高输出信噪比; Simulation shows that this method does not need a priori information of can restrain the interference in blind beamforming, the OFDM signal to obtain high gain of main lobe upwards, then to improve the output SNR;
6815 另外,所提的波束形成方法在输入信噪比较低的环境下依然能够形成稳定的波束,将主瓣对准信号来向。 In addition, the proposed beamforming method is still in the input of low SNR environment can form stable beam, to aim the main lobe signals.
6816 针对多情景混合型的风险决策问题,考虑决策者期望和心理行为特征,提出一种基于效用风险熵的决策分析方法。 According to multiple scene hybrid risk decision problem, consider policymakers expect and psychological behavior characteristics, in this paper, a decision analysis method based on utility risk entropy.
6817 首先,分析并总结多情景混合型风险决策信息的结构特征; First of all, analyze and summarize the structure of multiple scenarios hybrid risk decision information characteristic;
6818 然后引入前景理论价值函数,将属性值与期望参照点对比,作为决策者所感知的"损益值",计算各结果情景下的综合效用价值; Then introduce the prospect theory value function, the attribute value is compared with expected reference point, "profit and loss value, perceived policymakers scenario synthetic utility value calculated results;
6819 进一步综合考虑结果情景效用价值及发生概率的双因素作用,通过直接定义效用风险系数和效用风险函数,基于效用风险熵对方案的整体效用风险大小进行度量并排序; Further considering the scene utility value and the probability of the double factors, through direct definition utility risk coefficient and risk utility function, based on utility risk entropy measure and scheme of the overall utility risk size sorting;
6820 最后,通过算例分析,验证该方法的合理有效性。 Finally, through case analysis, verify the reasonable effectiveness of the method.
6821 为了实现防空反导目标识别,根据证据折扣理论和证据可靠性评估的思想,提出了一种改进的时域证据组合方法。 In order to realize air defense missile target recognition based on evidence theory and evidence discount the thought of reliability evaluation, put forward an improved time domain evidence combination method.
6822 首先,提出了具有时域信息累积的信息融合模型; First of all, with time domain information accumulated information fusion model is put forward.
6823 然后,通过基于信任度和虚假度的方法对累积的时域信息进行预处理,用可信度衰减模型和基于Einstein算子改进的冲突因子分别进行实时可靠性和相对可靠性评估; Then, through the method based on trust and false degree to the accumulation of time domain information preprocessing, with credibility attenuation model and the improved conflict factors respectively based on Einstein operator in real-time reliability and relative reliability evaluation;
