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

1、 生产者―消费者问题是一种同步问题的抽象描述。 2、 计算机系统中的每个进程都可以消费或生产某类资源。当系统中某一进程使用某一资源时，可以看作是消耗，且该进程称为消费者。 3、 而当某个进程释放资源时，则它就相当一个生产者 -one, producer-consumer problem is a problem of synchronization of the abstract description. 2, the computer systems of each process can consumption or production of certain resources. When a process system using a resource, can be seen as expendable, and the process known as consumers. 3, and when a process to release resources, then it is a producer
