CvEM::COV_MAT_DIAGONAL - a covariation matrix of each mixture may be arbitrary diagonal matrix with positive diagonal elements, that is, non-diagonal elements are forced to be 0's, so the number of free parameters is d for each matrix.

每一个混合的协变矩阵都是任意的正对角阵，也就是说，非对角位置的值必须是0，因此每一个矩阵的自由参数为d。

The main job and contribution of this paper are as follows:Based on narrowband signal processing, we propose a new method for FH signal blind detection and blind parameter estimation. Firstly, compute the cross-correlation function of FH signals from multichannels, then we get the cross power spectral density matrixCSDM Secondly, select the hops of FH signals from the CSDM via processing and analyzing the CSDM, meanwhile reduce the influence coming from noise, fixed frequency signal and other interferences; Lastly, estimating the DOA of every hop and according to the DOA, we can separate the hops, get the number of FH signals and their parameters. Propose a new method for designing the threshold in FH signal detection. This method makes it easy to get the threshold by theoretic computing and it can extremely reduce the interference of non-FH signals.Based on broadband signal processing, we propose a new method for FH signal blind detection and blind parameter estimation. Firstly, get the DOA of the signals by wideband spatial spectrum estimation; secondly, separate the signals by spatial filtering using wideband beamformer; Lastly, we propose two methods for FH signal blind detection and blind parameter estimation, one is for several constant hop-rate FH signals whose dwell-time are different and another is for a single FH signal whose hop-rate is alterable.By employing spatial interpolation in broadband signal beamforming, it can reduce the number of antenna elements and corresponding RF modules, A/D converters, etc. It can also eliminate the mutual coupling between antenna elements while getting the narrower main beamwidth and lower sidelobe level.

本文的主要研究工作和贡献如下：●提出了一种基于窄带处理的FH信号盲检测和参数盲估计的实现方法，即首先求出多路信号之间的互相关，进而得到互功率谱密度矩阵，然后通过对CSDM进行对折处理来抑制噪声、定频信号及其他干扰的影响，并将所有属于FH信号的hop(每一跳的驻留时间在时频图上持续的线段)从CSDM中筛选出来，最后用阵列信号处理中的到达方向估计理论在频域中估计出各个hop的方向参数，利用方位信息完成FH信号分离并得到FH信号的数目及其各自的参数集；●提出了一种确定FH信号检测门限的策略，该策略不仅使得检测门限能够通过理论计算得到，而且还显著地抑制了非跳频信号的干扰，从而能有效地检测出FH信号；●提出了一种基于宽带处理的短波FH信号盲检测和参数盲估计的实现方法，即首先利用宽带空间谱测向技术得到接收信号的DOA，然后采用宽带波束形成技术对特定方向进行空间滤波，实现多个信号的分离，最后分别提出了两种FH信号的盲检测和参数盲估计方法，第一种方法适用于空间某个特定方向上存在着几个驻留时间不同的恒跳速FH信号和其他干扰信号的混合信号，第二种方法适用于空间某个特定方向上仅含一个可变跳速的FH信号和噪声的混合信号；●将空间插值的概念和宽带波束形成技术结合起来，提出了一种基于频域处理的宽带恒定束宽的波束形成方法。

Many of the elements below each constraint element PRO_E_DTMPLN_CONSTRAINT are used only for certain constraint types, so any given datum plane may contain fewer elements than are shown in the tree.

许多下面每个约束元素 PRO_E_DTMPLN_CONSTRAINT 只使用确定的约束类型，所以任何给定的基准平面可能包含比树里看到的少些的元素。

Instead, the vector must allocate new memory to hold the existing elements plus the new one, copy the elements from the old location into the new space, add the new element, and deallocate the old memory.

于是， vector 必须重新分配存储空间，用来存放原来的元素以及新添加的元素：存放在旧存储空间中的元素被复制到新存储空间里，接着插入新元素，最后撤销旧的存储空间。

Objective elements: for example, the density of elements, 25%, 50% and 75% of the superimposition of plinthitic, as well as other can use densitometer or other color measurement equipment evaluation element.

不不主观元素：例如密度元素、25%、50%和75%的网纹、叠印色以及其他可以用密度计或其他色彩丈量摆设评估的元素。

Inserts an element or a number of elements or a range of elements into the deque at a specified position.

插入一个元素或多项要素，或到deque的一个范围的元素在指定位置。

The invention relates to a support for functional elements (1), especially a pocket knife or a tool, comprising a receiving body (2) having two opposing side walls (18, 22) which are arranged at a distance from each other by means of narrow side surfaces (16, 17) and front surfaces (6, 7), in addition to a cover plate (10) which is held on at least one of the side walls (18, 22), also comprising receiving chambers (33) which are used to detachably maintain functional elements such as tools, knives and scissors.

本发明涉及一种功能部件收贮体(1)，特别是折叠刀或者工具插板，其具有一个容纳体(2)，该容纳体带有两个相对置的侧壁(18、22)，这两个侧壁被窄侧面(16、17)和端面(6、7)彼此隔开，在两侧壁(18、22)中的至少一个上设置一个盖板(10)，并带有容纳空腔(33)，用于可取下地容纳功能部件，例如工具、刀、剪刀。

According to this characteristic, the search matching method of this diagonal line in this calculation is to regard the main diagonal lines as the superior searched route, discard the elements far from the main diagonal lines and it won't generate matching matrix when actually realized. Just regard the present search point as the start point, search matching elements at the small rectangle from the bottom right, regard the element when found as the new start point, so this can happen repeatedly until the ends of the two strings.

根据这个特点，本算法中的对角线搜索匹配算法以主对角线为优先搜索路径，抛弃了离主搜索路径太远的元素，实际实现时，并不需生成匹配矩阵，只以当前搜索点为起点，向右下方向一个小矩形区域上搜索匹配的元素，找到匹配的元素后即以该元素为新的起点，这样无回溯地重复进行直到两个串的未尾为止。
