这是我从网看到的，不用电平的转换IC就可以把串口TTL输入、输出的电平转换成计算机能识别的电平，原图经测试不能用，经我改进后效果很好，大家不妨一试-This is what I see from the network, not power conversion IC level can be the serial TTL input and output level into the computer to identify the level, the maximum should not have been tested, and improved by my very good , we may as well try

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
