Two scripts are included here. 1. convsys.m - combines the state space representation of two systems connected in series. [Ao,Bo,Co,Do]=convsys(A1,B1,C1,D1,A2,B2,C2,D2) This algorithm gives the convolution of two state space representations | A1 B1 | | A2 B2 | u ==> | | ==> | | ==> y | C1 D1 | | C2 D2 | The algorithm also accepts state space objects as inputs and gives out a state space object as output. 2. sysfeedbk.m [Ao,Bo,Co,Do]=convsys(A1,B1,C1,D1,A2,B2,C2,D2) Gives the closed loop state space representation for two systems connected with negative feedback in the following manner. | A1 B1 | u ==> | | ==> y + o | C1 D1 | | - | | | | A2 B2 | | |= | |= | | C2 D2 | The zip file also contains checkcompatibility.m , which checks the compatibility of matrix dimensions in the system and cleanss.m which can be used to clean a state space representation.

这个程序是实现人工智能中的A*算法，照着书上的算法做的。Queue类是自己写的一个队列类，用来实现open表和closed表。原来用Vector做的，但后来发现Vector中保存的只是引用，生成子状态后表中的状态也跟着变了，只好自己实现一个队列类。

Regardless of the branch of science or engineering, theoreticians have always been enamored with the notion of expressing their results in the form of closed-form expressions. Quite often, the elegance of the closed-form solution is overshadowed by the complexity of its form and the difficulty in evaluating it numerically. In such instances, one becomes motivated to search instead for a solution that is simple in form and simple to evaluate.

During the past decade, many wireless communication techniques have been developedto achievevariousgoals suchas higherdata rate,morerobustlink quality, and higher number of users in a given bandwidth. For wireless communication systems, depending on the availability of a feedback link, two approaches can be considered: namely open and closed loop. Open loop communication system that does not exploit the channel knowledge at the transmitter is now well understood from both a theoretical and practical point of view.

This books attempts to provide an extensive overview on Long-Term Evolution (LTE) networks. Understanding LTE and its Performance is purposely written to appeal to a broad audience and to be of value to anyone who is interested in 3GPP LTE or wireless broadband networks more generally. The aim of this book is to offer comprehensive coverage of current state-of-the-art theoretical and techno- logical aspects of broadband mobile and wireless networks focusing on LTE. The presentation starts from basic principles and proceeds smoothly to most advanced topics. Provided schemes are developed and oriented in the context of very actual closed standards, the 3 GPPP LTE.

三极管除了可以当做交流信号放大器之外， 也可以做为开关之用。严格说起来， 三极管与一般的机械接点式开关在动作上并不完全相同， 但是它却具有一些机械式开关所没有的特点。图1所示，即为三极管电子开关的基本电路图。由下图可知，负载电阻被直接跨接于三极管的集电极与电源之间，而位居三极管主电流的回路上。输入电压Vin 则控制三极管开关的开启(open) 与闭合(closed) 动作，当三极管呈开启状态时， 负载电流便被阻断， 反之， 当三极管呈闭合状态时， 电流便可以流通。详细的说，当Vin 为低电压时，由于基极没有电流，因此集电极亦无电流，致使连接于集电极端的负载亦没有电流，而相当于开关的开启，此时三极管乃胜作于截止(cut off) 区。
