[Documents] The-Introduction-Of-OFDM-Spectrum DL : 0: 本文介绍了OFDM技术及其功率谱的，并通过仿真研究了OFDM的功率谱密度特点。在同样条件下，增大子载波数目，会使信号带宽增加，带外衰减加快，功率谱密度图形更加接近于矩形。另外，添加循环前缀将使离散峰值谱线的值略微增大。-This article describes the OFDM technology and its power spectrum, and to study the characteristics of the power spectral density of the OFDM simulation. Under the same conditions, increasing the number of subcarriers, and will increase in signal bandwidth, band attenuation accelerate, and power spectral density pattern closer to the rectangle. Further, the cyclic prefix is added the value of the discrete peak spectrum will increase slightly......

[Documents] Class-definition DL : 0: 写一个名为Rectangle的类表示矩形。属性为宽width、高height和颜色color，widthhe height是double型的，color是String型的。假定所有矩形颜色相同，用一个类变量（类属性）表示颜色。要求提供访问器方法和计算矩形面积的findArea()方法。写一个用户程序测试Rectangle类：创建两个Rectangle对象。给两个对象设置任意的宽和高。设矩形颜色为黄色。显示两个对象的属性并求面积。 -Write a rectangle representing a class named Rectangle. Property wide width, height and color of high color, widthhe height is double type, color type is String. Assume the same color all the rectangles representing the color variable with a class (class attribute). We requested access methods and calculation area of a rectangle findArea () method. Write a program to test user Rectangle class: create two Rectangle objects. Two objects to set any width and height. Let rectangle color is yellow. Two display object' s properties and find the area.

[Documents] 图形的周长和面积计算器C_.doc DL : 0: 为了大家更方便的计算图形的周长和面积，我设计了一个实现图形的周长和面积的计算器。这个计算器可以计算圆形、矩形、三角形的周长和面积。用户输入圆的半径或者矩形的长和宽或者三角形的三边长，系统判断用户输入的是否正确，若不正确，给出提示；若正确，系统会计算出相应的周长和面积，并显示在屏幕上反馈给用户。(In order to calculate the circumference and area of the graph more conveniently, I designed a calculator to realize the perimeter and area of the figure. This calculator can calculate the perimeter and area of a circle, rectangle, triangle. If the user input the radius of the circle or the length and width of the rectangle or the three sides of the triangle, the system judges whether the user input is correct, if not correct, gives the prompt; if correct, the system accounting calculates the corresponding perimeter and the area, and displays on the screen feedback to the user.)

[Documents] acm DL : 0: A message from humans to extraterrestrial intelligence was sent through the Arecibo radio telescope in Puerto Rico on the afternoon of Saturday November 16, 1974. The message consisted of 1679 bits and was meant to be translated to a rectangular picture with 23 * 73 pixels. Since both 23 and 73 are prime numbers, 23 * 73 is the unique possible size of the translated rectangular picture each edge of which is longer than 1 pixel. Of course, there was no guarantee that the receivers would try to translate the message to a rectangular picture. Even if they would, they might put the pixels into the rectangle incorrectly. The senders of the Arecibo message were optimistic.(The input is a sequence of at most 2000 triplets of positive integers, delimited by a space character in between. Each line contains a single triplet. The sequence is followed by a triplet of zeros, 0 0 0, which indicated the end of the input and should not be treated as data to be processed. Input The integers of each input triplet are the integer m, the numerator a, and the denominator b described above, in this order. You may assume 4 < m <= 100000 and 1 <= a <= b <= 1000. Output The output is a sequence of pairs of positive integers. The i-th output pair corresponds to the i-th input triplet. The integers of each output pair are the width p and the height q described above, in this order.)

[Documents] 搜索1003 DL : 0: The doggie found a bone in an ancient maze, which fascinated him a lot. However, when he picked it up, the maze began to shake, and the doggie could feel the ground sinking. He realized that the bone was a trap, and he tried desperately to get out of this maze. The maze was a rectangle with sizes N by M. There was a door in the maze. At the beginning, the door was closed and it would open at the T-th second for a short period of time (less than 1 second). Therefore the doggie had to arrive at the door on exactly the T-th second. In every second, he could move one block to one of the upper, lower, left and right neighboring blocks. Once he entered a block, the ground of this block would start to sink and disappear in the next second. He could not stay at one block for more than one second, nor could he move into a visited block. Can the poor doggie survive? Please help him.(The input consists of multiple test cases. The first line of each test case contains three integers N, M, and T (1 < N, M < 7; 0 < T < 50), which denote the sizes of the maze and the time at which the door will open, respectively. The next N lines give the maze layout, with each line containing M characters. A character is one of the following: 'X': a block of wall, which the doggie cannot enter; 'S': the start point of the doggie; 'D': the Door; or '.': an empty block.)
