11484 首先类比事故树基本事件重要度,建立能综合反映指标重要度的模型及改善代价的模型; ‭Basic event importance first analogy of accident tree, can establish comprehensive reflection index important degree model and improve the cost model;
11485 之后对最大重要度所对应指标得分进行固定步长、渐升步长以及渐降步长等3种形式的增值。 After the maximum importance index score which corresponds to a fixed step length, rising step as well as the gradual decline step length and so on 3 kind of appreciation.
11486 再求新的系统评价得分,直到系统评价满足阈值,并确定3种迭代模型的取舍策略; And seeking, the score of the new system meet the threshold until the system evaluation, and to determine three iteration model of trade-off strategy;
11487 最后分析迭代过程及结果,建立指标改变先后度模型,确定指标改变的轻重缓急次序。 In the final analysis the iterative process and results, establishes the index change successively degree model, determine the priorities of the index change order.
11488 文中以模糊综合评价方法为对象分析,实例验证切实可行,并可推广应用于灰色评价、可拓学评价以及集对分析等常规评价方法。 ‭With fuzzy comprehensive evaluation method for the analysis of object, the instance validation is feasible, and can be applied in grey evaluation, evaluation of extenics, the set pair analysis of conventional evaluation methods, etc. ‭
11489 空时码应用最广泛的是空时分组码(space-time block code,STBC)和垂直分层空时码(vertical bell layered space-time code,VBLAST),因为STBC信号具有时间上的相关特性,所以在求高阶循环累积量时,该信号有一个特殊的循环频率,而VBLAST信号没有此特性。 Space-time code is the most widely used space-time block codes (STBC, space - time block code) and vertical layered space-time code (vertical bell layered space - time code, VBLAST), because of STBC signal with time on relevant properties, therefore, when strives for the high-order cyclic cumulants, the cycle of the signal has a special frequency, and VBLAST signal without this feature.
11490 提出了一种基于循环稳定特性的STBC多载波码分多址(multicarrier code division multiple access,MC-CDMA)信号识别算法。 Is put forward based on the cycle stability characteristics of STBC multicarrier code division multiple access (multicarrier code division multiple access, Mc-cdma) signal recognition algorithm.
11491 该方法先根据信号系统的基带物理结构和信号模型来建立信号相关函数的选择标准; The method according to the baseband signal system first physical structure and signal model to establish the signal correlation function selection criteria.
11492 然后估计出这些相关函数对应的四阶累积量; And then estimate the correlation function corresponds to the fourth order cumulants.
11493 接着把四阶循环累积量跟信道的参数结合起来建立一个循环统计量; Then put the fourth-order cyclic cumulants combined with the parameters of the channel to set up a cyclic statistics.
