the paper introduces long curtate new unequal ofdm system.adopts long curtate unequal benefit to be not to require that the second order adding the circulation prefix,being therefore likely to lead into period stationarity,making use of signal therefore in launching an array,counting characteristic property realizing blind estimation of route.this technology includes three kinds of method : subspace decomposition,correlation matching,and maximum likeewise,monte carlo simulation show that whentheeb/no is low,function is better than the other kinds of method.

摘 要：提出一种采用不等长分组新的ofdm系统。采用不等长分组的好处是不需要加循环前缀就能在发射序列中引入周期平稳性，因此，可利用信号的二阶统计特性实现信道盲估计。信道盲估计主要分子空间分解、相关拟合和最大似然三种方法。结合monte carlo仿真表明，在信噪比较低时，结合子空间分解方法计算出的误码性能比其余两种方法好。

Simulation results show that the proposed algorithm has a faster convergence rate and much less computational complexity, and the output bit error rate and signal-to interference-plus noise ratio performance are superier to the PASTd blind multiuser detection algorithm and close in on the singular value decomposition group blind multiuser detection algorithm.

仿真结果表明，所提算法收敛速度快，输出信干噪比和误码率性能优于PASTd盲多用户检测，逼近奇异值分解(singular value decomposition， SVD)群盲多用户检测，并保持了较低的计算复杂度。

One is the lacking of suitable social context, restrained by Confucianism tradition of pragmatism. The other is the irrational fanatic circumstance after the 'Culture Revolution'. This resulted in the fact that science cannot perfect itself for its own sake at all and the intellectuals cannot stand on their dignity. The other is the hypercorrection of science people made. This turned science into 'God' in their mind. The fanaticism resulted in scientism in science circle and the prevailing pseudoscience in society.

究其原因，主要有几个方面：一是中国传统文化对科学技术的制约，"经世致用"的儒教传统使科学很难有健康发展的土壤；二是"文革"期间失去理性的社会环境，使科学根本不可能独善其身，科学技术和知识分子的人格尊严被无情的践踏；三是"文革"过后人们对科学的矫枉过正，这使得科学成为人们心目中的"上帝"，对科学的盲信导致了科学界"唯科学主义"的诞生和"伪科学"在社会中的盛行，并且科学对社会的危害也日益在引起人们的高度重视。

PCA is not only used as feature extracting method (where process variables are subjected to multivariate normal distribution), but also as a tool for dimension reduction; BSA is used to extract independent features or process blind source signals from process information in information theory sense, which is more effective than PCA in describing the process.

主元分析方法不仅作为一种过程特征的提取方法（在过程信息服从多元正态分布的情况下），而且也作为一种过程数据降维的主要工具（在过程盲源信号提取的情况下）；盲源信号分析是从信息论的角度，从过程信息中提取出尽可能独立的过程特征信号或过程原始信源信号，它具有比主元分析更好的刻画过程运行特征的性能。

He supposedly cured the jailer's daughter of her blindness. The night before he was executed, he wrote the jailer's daughter a farewell letter, signing it "From Your Valentine."

据说，他医好了狱卒的盲眼女儿，他被行刑前的那个晚上，写下了给狱卒女儿的诀别信，签上了"你的瓦伦丁"这样的名字。

Simulation results show that RLS algorithm is of great convergence performance, stable SIR and accurate tracking, but high complexity.

主要工作可以概括如下：(1)对盲多用户检测的LMS算法、RLS算法的信干比、最小输出能量进行了分析、研究和仿真。

From Diognetus, not to busy myself about trifling things, and not to give credit to what was said by miracle-workers and jugglers about incantations and the driving away of daemons and such things; and not to breed quails for fighting, nor to give myself up passionately to such things; and to endure freedom of speech; and to have become intimate with philosophy; and to have been a hearer, first of Bacchius, then of Tandasis ?

第欧根尼给我以教诲，让我不忙碌于琐事，不盲信于精灵鬼怪和符咒魔道之类的事物，训练我不畏缩于战斗，从不放弃对诸事充满激情；他还教我容忍言论自由，尽可能亲近哲学，学会尽量去倾听，从巴克斯开始，然后就是坦德西斯和马西昂；年轻的时候我就开始学写对话；我渴望承受生活的磨砺，对古希腊风范的生活种种兴趣盎然。

By means of the preprocessing technique, the well known space smoothing method and MODE method which can only be used to ULA can then be applied to VULA to estimate DOA's of coherent sources.

盲估计算法是在整个模型空间内寻找与相干信源对应的广义方向向量，然后再由广义方向向量估计各个相干信源的方向。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
