The most straightforward approximation is the standard Gaussian approximation, where the MAI is approximated by a Gaussian random variable. This approximation is simple, however it is not accurate in general. In situations where the number of users is not large, the Gaussian approximation is not appropriate. In-depth analysis of must be applied. The Holtzman?s improved Gaussian approximation provides a better approximation to the MAI term. The approximation conditions the interference term on the operation condition of each user.

摘要:实战条件下如何评价短波跳频通信系统的抗干扰性能是构建短波跳频通信系统的重要环rr-}J。由于不 能得到精确的指标评价值，采川组合赋权法给出了系统抗干扰性能的评价算法已经不能适川。给出了一种模糊综 合评价方法，该方法有如下优点:为避兔专家赋指标权值的卞观随意性，将德尔菲(Delphi)法和层次分析法(AHP)相结合来确定指标权值 为了便于专家较准确地作出评判，给出了指标评价等级，并利川模糊评价法给出指标评价矩 阵，最后得到评价结果。评价实例表明了该方法的有效性。 -Abstract: how to assess the actual conditions of short-wave frequency-hopping communication system anti-jamming performance is short-wave frequency-hopping communication system to build an important ring rr-) J. Can not be accurate due to evaluate the value of mining Kawasaki combination weighting approach gives a systematic evaluation of anti-interference performance can no longer be appropriate algorithm Chuan. This paper presents a fuzzy comprehensive evaluation method that has the following advantages: In order to avoid the rabbit experts give the right indicator of the value of randomness Bian concept will Delphi (Delphi) and Analytic Hierarchy Process (AHP) to determine the combination of the right indicators value in order to facilitate t

擅 蔓：以人脸的表情识别为实验背景， 分析了在对人脸表情的识别过程中，单个独立分薰对识别率的影响，由此进一步总结了在表情识 别中如何更有效地选取独立子空间，以实现在不影响识别率的前提下，减少用于构成独立子空问所需的独立分量的个数。 独立成分分析；表情识别；独立子空间 -Good man: Face to face identification for the experimental background, the analysis of facial expressions in the identification process, a single smoked separate the impact of the recognition rate, thus further summarized in the expression recognition of how to more effectively select the independent sub-space in order to achieve the recognition rate does not affect the premise, for constituting a separate sub-reducing space required for the number of independent component. Independent component analysis expression recognition independent subspace
