实现的

First, mathematical foundation of synchronization, i.e. the theory of parameter estimation is introduced. Then, DA/DD or NDA timing synchronization methods based on the ML estimation of timing parameter are presented. They are all widely applied in actual digital communication systems. Interpolation theory in digital signal processing has application in timing synchronization, which makes the sampling clock independent of the timing control so that timing adjustment is realized completely through digital disposal. The issue of interpolation in timing synchronization is discussed.

首先，介绍了定时同步实现的数学基础，即信号参数估计理论；从定时参数的最大似然估计出发，介绍了基于数据辅助的定时同步方法和基于非数据辅助的定时同步方法，他们在实际的数字通信系统中均有广泛应用；论文探讨了数字信号处理中插值理论在定时同步中的应用，它使得接收端的采样时钟独立于定时控制，定时调整完全通过数字处理方法得以实现。

图5.1中的供给曲线线段没有确切的定义；如果曲线左边的各点是可实现的，那么它是"向后弯曲"的供给曲线；如果曲线上面的各点是可实现的，那么它是"向前下降"的供给曲线。

The seeds of discontent were planted by Adolph Berle and Gardiner Means (1932) in relation to the separation of ownership from control, by Ronald Coase (1937) with reference to the puzzle of vertical integration and the theory of the firm, by Chester Barnard (1938), who featured adaptation of a cooperative kind accomplished through hierarchy (as opposed to adaptation through the market in response to changes in relative prices), by the 'marginalist controversy' of the 1940s, and by Armen Alchian's (1950) appeal to evolutionary arguments to explain observed economic regularities.

不满的种子由此而种下，例如， Adolph Berle 和 Gardiner Means （1932）有关所有权和控制权分离的研究， Ronald Coase （1937）对纵向一体化难题和企业理论的关注， Chester Barnard （1938）对一种通过层级实现的合作式调节方式（相对于通过市场响应相关价格改变而实现的调节方式）的强调，20世纪40年代的"边际主义论战"，以及 Armen Alchian （1950）对用演进观点来解释观察到的经济规律的呼吁。

In this thesis, soft starter equipment realized by thyristors power transform circuit is studied. To improve equipment performance, we apply variable reactance technique to AC motor soft starter study. The high voltage AC working winding of reactance is in series with motor winding, while low voltage control winding and thyristors groupware with intelligent controller constitute close loop circuit. We adopt thyristor phase control voltage-regulator mode to control low voltage winding, then control the reactance of high voltage winding, and then arrive at the goal-control the current and voltage of motor AC to realize motor soft starting.

The multipath effect is an avoidless problem which the tracking radar and the searching radar among CIWS has to face. This paper analyses the form of the multipath effect on geometry, emphasizes the distance difference between the direct wave and the reflected wave, according to this inherent characteristic, the paper introduces the theory of HRR to the design of radars among CIWS, discusses the spike pulse technology and ultra wide hand technology which often be used, finally proposes the method of time-frequency code to obtain the high range resolution and avoid the multipath effect.

多路径效应是近程反导武器系统中的搜索雷达和跟踪雷达均无法避免的问题，文中分析了多路径效应形成的几何原理，并根据多路径效应中的直射波与反射波具有路程差的固有特性，将高距离分辨率雷达信号理论引入到近程反导武器系统的雷达中，讨论了实现高距离分辨率的窄脉冲和超宽带技术，最后提出了目前较易实现的时间－频率码合成高距离分辨率的办法。
