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
