摘要
提出采用自适应干扰对消技术，解决电气化铁路牵引电流对地面与机车间信号信息传输的干扰问题，建立了牵引电流干扰模型。由于牵引电流干扰是在一定时间间隔内是平稳的，采用自适应干扰对消器可有效抑制牵引电流干扰。给出了有关实现轨道信号抗干扰的仿真结果。
The technique of adaptive noise canceller has been proposed to solve the problem of interference of tractive current to the signal between ground and the cab in electric railway. The model of interference of tractive current has been established. Since the interference is smooth in some time interval, it is possible to adopt the adaptive noise canceller to suppress the interference effectively. Simulation result for the implementation of the technique anti- interference has been provided.
