摘要利用初等矩阵与初等变换的对应关系及分块矩阵的乘法，给出“矩阵的行初等变换不改变其列向量组的线性关系”的一个简易证明。 - Traditional delay estimation based on ica requires the trail sequences to initialize the receiver , but the new algorithm based on ica does not need the trail sequences . it is based on the channel character of downlink , using the ica algorithm to estimate the multi - path mixture matrix , then , find the delay information which is embodied by the column vector of the mixture matrix . the simulation results show that it does enhance the performance of traditional detector without wasting the invaluable frequency resource
传统的信道估计算法需要训练序列使接收端的参数调整到理想状态，而本文提出的基于ica的信道估计的多用户检测算法不需要训练序列，它是利用下行信道的固有特点，用ica的盲源分离法估计出多径信道的卷积矩阵，从而从中提取出信道的延迟信息，仿真实验结果证明这种方法在节省了频谱资源的同时取得较好的估计效果，使得传统的接收机的误码性能得到了很大的提高。 - In the preprocessing stage the method of user and session identification often adopt heuristic algorithm for the being of cache and agent . this induce the uncertainty of data resource . the cppc algorithm avoid the limitation and has no use for complicated hash data structure . in this algorithm , by constructing a userld - url revelant matrix similar customer groups are discovered by measuring similarity between column vectors and relevant web pages are obtained by measuring similarity between row vectors ; frequent access paths can also be discovered by further processing of the latter . experiments show the effectiveness of the algorithm . in the fourth part , this thesis bring some key techniques of data mining into web usage mining , combine the characteristic of relation database design and implement a web usage mining system wlgms with function of visible . lt can provide the user with decision support , and has good practicability
本文算法避免了这个缺陷，且不需要复杂的hash数据结构，通过构造一个userid - uel关联矩阵，对列向量进行相似性分析得到相似客户群体，对行向量进行相似性度量获得相关web页面，对后者再进一步处理得到频繁访问路径。实验结果表明了算法的有效性。第四是本文将传统数据挖掘过程中的各种关键技术，引入到对web使用信息的挖掘活动中，结合关系数据库的特点设计并实现了一个具有可广西人学颀士学位论义视化功能的web使用挖掘系统wlgms 。 - The input and output state vectors are defined , which are a 6 1 column vector including motion types , the magnitude and spatial orientation , respectively . the state matrices ( sms ) can be deduced by vectors operation , that is , the output state vectors multiplied by the input state vectors
其中，前者按照输入输出端的不同运动类型、速度矢量的大小及方向特征，以6维矢量形式表示；而后者作为输入、输出特征矢量之间的纽带，描述了基本变换单元的功能与特征。 - In the subsystem of signal processing , digital sidelobe cancell block , digital pulse compress block , adaptive clutter canceller block , doppler filter and constant false alarm rate block are respectively discussed and set up . in signal processing , data in the same coherent processing interval form a matrix , and the data processing was completed based on the matrix . data are processed with the row vector or column vector respectively when needed
在信号处理分系统中，将脉冲压缩得到的数据在各个相干处理区间进行处理，将一个相干处理区间的数据按照不同的脉冲重复周期和不同的距离单元排列成一个矩阵，当需要实现数字脉冲压缩时对矩阵的各行(同一个脉冲重复周期的数据)进行处理，当需要实现多普勒滤波时，就对矩阵的各列(同一个距离单元的数据)进行处理。
