| 摘 要： | 在广播线信道上选择合适的通信方式对保障铁路客车发电机监测系统稳定通信具有重要意义。结合广播线信道的强干扰性及衰减特性,基于正交频分复用（OFDM）通信方式,建立一个新的广播线信道简化模型。仿真结果表明,相比传统通信方式,OFDM通信应用于广播线通信信道上具有衰减较少,误码率较低的特性。

| Abstract: | Selecting an appropriate communication in the broadcast cable channel is of great importance to protect a stable communication of railway carriage generator monitoring system. In combination with strong interference and attenuation characteristics of the broadcast cable channel, a new simplified model of broadcast cable channel is set up based on OFDM communication. Simulation results show that OFDM communication is used in broadcast communication cable channel with less attenuation and low error rate compared with traditional means of communication. |
