Especially, the combined ratio estimator of domain total is investigated under stratified complemental sampling when auxiliary information can be used.

及该方案在分层抽样下的推广，在有辅助信息可用时构造域总量的分层联合比估计，并给出其方差和方差估计公式，同时我们给出了模拟结果，从模拟结果可以看出，给出的方差估计是估计量方差的近似无偏估计。

to reduce the impact of carrier frequency offset in ofdm system,this thesis designs a new carrier frequency offset estimation scheme for ofdm system.the carrier frequency offset estimation includes acquisition and tracking.we adopt variable step size adaptive algorithm.the acquisition range of the proposed algorithm is as large as one half of the overall signal bandwidth.through this method we can not only avoid the feedback by using forward error correction,but also reduce the times of complex multiplication in order to reduce the power consumption of the system.this algorithm not only has low complexity and fast convergence nut also can improve the demodulation performance of ofdm system.computer simulation illustrates the superior performance of the proposed algorithm with regard to estimation accuracy in both awgn channel and multi—path channel.

摘 要：为了减小正交频分复用系统受频率偏差的影响，在ofdm系统中设计了一种新的载波频偏估计算法。频偏估计包括跟踪和捕获两个阶段，文中采用变步长自适应算法来进行跟踪，这个跟踪算法的捕捉范围是整个信号带宽的一半。通过此方法，不但可以利用前向纠错的方式来避免反馈，而且可以缩减复数乘法的次数以降低计算复杂度和系统功耗。该方法运算复杂度低，并具有较好的收敛性，能改善odfm的解调性能。从计算机的仿真效果可以看出无论是在awgn信道上还是在多径信道上都表现出了卓越的性能。

This is his first time, so you can see his complexion is ghost-like.

This dissertation presents three segmentation algorithms for compressing image documents, with a high compression ratio of both color and monochromatic compound document images. The proposed algorithms greatly outperform the famous image compression methods, JPEG and DjVu, and enable the effective extraction of the text from a complex background, achieving a high compression ratio for compound document images.

本文中提出的切割方法应用於文件影像压缩，可以明显的看出压缩倍数与视觉品质优於JPEG或DjVu，而且在本文第三个切割方法中，提出新的区域性区块特徵分离与拼图式全图整合的方法，在解决复杂型复合式文件影像的文字切割问题时，即使在同一张完整的文件影像中，包含各种不同程度的复杂状况，也可以顺利的将不同颜色、不同复杂背景与不同交叠程度的文字切割出来，提高各种复杂型复合式文件影像的压缩品质。

If be its rise and fall to fall,draw on one piece of graph, slightly computative can see,.

假如为它的起起落落画上一张曲线图，稍加推算就可以看出，。。。

As a matter of fact, from this definition, we find it is one kind of active mental and conceptive management.

其实，从这个定义当中我们看出企业是心智的活动，理念的管理。

The child's father seemed to see a child's mind, he had arranged his comfort children, children don't worry, indeed, wily conciliator, he should know, in this city, he is a successful businessman.

孩子的父亲似乎看出了孩子的心事，他安慰孩子自己早有安排，叫孩子不必担心，的确，老谋深算是他的本领，要知道，在这个城市，他可是个非常成功的商人。

When three kinds of environmental texts are analyzed in the ecocritical perspective,the development of human history is considered to be in concomitance with environmental history.

从生态批评研究的多种"环境文本"可以看出，生态批评试图召唤一种阅读语境的根本性转换——从人类唯我独尊的语境转换到一个"地球大生态圈"视阈中的环境语境。

It is clear that these scholars were just trying to provide an epistemological interpretation for the Confucianist morality.

可以看出，这些学者所试图做的，是对儒学的道德思想提供一种彻底的认识论的解释。

She saw the confusion on my face and told me, This question is very important.

她看出了我的困惑，并告诉我，这个问题很重要。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
