摘要:基于通信技术的列车运行控制系统(CBTC)是铁路信号的发展方向,交频分复用
OFDM)是一种无线环境下的高速传输技术,它对高速列车控制信息传输中卞要受到的由于多
径传播引起的快衰落所产生的影响有很强的抵抗能力.本文首先介绍了OFDM技术的发展和
基本原理,然后在计算机上用M atlal〕对其性能进行了仿真,仿真中将OFDM与传统的单载波
调制方式―i1,交振幅调制( 1frQAM)对抗多径十扰的性能进行了比较,最后分析了一者的仿真结果.
-Abstract: Based on the communication technology train operation control system (CBTC) is a railway signal direction for the development of cross-frequency division multiplexing OFDM) is a wireless environment of high-speed transmission technology, its high-speed train control information transmission Bian be subject to the Due to the spread of multi-path fast fading caused by the impact of a strong resistance to diseases. This paper first introduces the OFDM technology development and the basic principles, and then on the computer〕 M atlal use its performance simulation will OFDM with the traditional single-carrier modulation-i1, cross-amplitude modulation (1frQAM) against multi-path interference of the 10 properties were compared with a final analysis of

学生成绩管理工作是学校学生管理工作的重要组成部分,现在相当一部分学校的学生成绩管理工作仍沿用手工方式。随着学校规模的扩大、学生人数的增加,效率低下、容易出错的手工方式越来越不适应实际管理工作的需要,按照软件工程原理和数据库技术开发学生成绩管理系统已成为学生管理部门的迫切需要。-student performance management is the management school students an important component, considerable part of the school management of student achievement is still used manual. With the increased scale of the schools, the number of students increases, inefficient and error-prone manual increasingly unable to meet the actual needs of management, in accordance with principles of software engineering and database technology student performance management systems have become students of management an urgent need.
