摘要
将自适应抵消系统运用于列车无线调度通信设备中，它能有效地削弱机车内环境噪声的影响，并在此基础上介绍了两种改进型的ＬＭＳ算法．
The adaptive noise cancelling system is applied to radio communication equipment of train disptching.The system can effectively cancel the noise of trains in the course of radio communication.and two modified LMS algorithms are also introduced.
