超声波测距
51单片机超声波测距,亲测能够使用,解释详细。主要技术参数:1.使用电压:DC5V 2.静态电流:小于2mA3:电平输出:高5V 4:电平输出:低0V5:感应角度:不大于15度 6:探测距离:2cm-450cm 7:高精度:可达3mm接线方式,VCC、trig(控制端)、 echo(接收端)、 GND地线使用方法:一个控制口发一个10US以上的高电平,就可以在接收口等待高电平输出.一有输出就可以开定时器计时,当此口变为低电平时就可以读定时器的值,此时就为此次测距的时间,方可算出距离.如此不断的周期测,就可以达到你移动测量的值了.模块工作原理:(1)采用IO触发测距,给至少10us的高电平信号;(2)模块自动发送8个40khz的方波,自动检测是否有信号返回;(3)有信号返回,通过IO输出一高电平,高电平持续的时间就是超声波从发射到返回的时间.测试距离=(高电平时间*声速(340M/S))/2;

正整数x 的约数是能整除x 的正整数。正整数x 的约数个数记为div(x)。例如,1,2,5,10 都是正整数10 的约数,且div(10)=4。设a 和b 是2 个正整数,a≤b,找出a 和b之间约数个数最多的数x。
对于给定的2 个正整数a≤b,编程计算a 和b 之间约数个数最多的数。
数据输入
输入数据由文件名为input.txt的文本文件提供。文件的第1 行有2 个正整数a和b。
结果输出
程序运行结束时,若找到的a 和b 之间约数个数最多的数是x,将div(x)输出到文件output.txt中。

-Positive integer x can be about a few of the positive integer x divisible. Positive integer x the approximate number recorded as the number of div (x). For example, 1,2,5,10 are about 10 positive integer number, and div (10) = 4. Set a and b are two positive integers, a ≤ b, to find a and b between about a few number of the largest number of x. For a given two positive integers a ≤ b, Programming calculated a and b between about a few number of the largest number. Data entry input data from the document text file named input.txt provide. File line 1 has two positive integers a and b. The results run the end of the output, if found between a and b of about a few number o

Pilot Contamination Reduction
应用背景This paper considers the problem of interference mitigation in multi-cell multi-antenna time division duplex (TDD) wireless systems for downlink transmission. An efficient way to obtain channel state information (CSI) at the base station is by using uplink pilots and reciprocity of the downlink channel.
At the same time, it has been shown that pilots from different cells contaminate each other, resulting in corruption of precoding matrices used by base stations, and high inter-cell interference. This paper studies the effects of shifting the location of pilots in time frames used in neighboring cells, and its effectiveness in obtaining better channel estimates, and, thereby, inter-cell
interference reduction.关键技术Wireless cellular network designs with multiple antennas have been adopted by several modern wireless systems, which aim for high throughput as well as high
