摘要:
 现代通信技术的一个重要特点是计算机技术与通信技术的紧密结合。随着计算机技术的迅速发展，对现代通信业也有更好的促进作用。借助计算机技术对通信技术的支持，对通信环境下的信道进行了测量与分析。传统移动蜂窝频段的严重短缺，使得高频段的开发与利用受到越来越多的关注与研究。采用基于PN序列的时域测量系统，在15 GHz频段下对室内走廊环境的直视场景进行了信道测量，分析了其大尺度特性，得到了距离和路径损耗的关系，并计算得出室内走廊环境下的路径损耗指数和阴影衰落。测量采用波束宽度为10o、增益为25 dBi的标准增益喇叭天线，通过改变发射天线俯仰角和接收天线水平角得到某个距离下的测量数据，分析了特定场景下接收功率随角度的变化特性。
Abstract:
 An important feature of modern communication technology is the close combination between the computer technology and com-munication technology. With rapid development of computer technology,the modern telecommunication industry is promoted. With the support of computer technology,the channel in communication environment is measured and analyzed. The shortage of traditional mobile cellular band makes the development of higher frequency paid more and more attention. In this paper,the time domain measurement sys-tem based on PN sequence is used to measure propagation characteristics of the line-of-sight scenarios in indoor corridor in 15 GHz. It analyzes the large scale characteristics,and presents the relationship between distance and path loss,and calculates path loss exponent and the shadow fading. In the measurement,two horn antennas with 10° HPBW ( Half-Power Beam Width) and 25 dB gain are used to change elevation angles in transmitting terminal and azimuth angles in receiving terminal in all measurement points. At the same time,it also analyzes the relationship between received power and different elevation angles.
