For electromagnetic interference caused by electric disconnection arc noise on GSM-R,we established a GSM-R interference channel model and improved GSM-R error control manner by using interleaving technique and RS-Turbo codes.The simulation results indicated that the channel model can reduce such kinds of noise interference and reduce the rate of system errors.%针对弓网电磁噪声对GSM-R的干扰,采用交织技术和RS-Turbo编码建立了GSM-R抗干扰信道模型,改善GSM-R差错控制方式。从仿真结果分析得出,采用的信道模型可以降低此类噪声干扰,降低系统误码率。
