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。
Aiming at the interference of bow network electromagnetic noise to GSM-R, GSM-R anti-interference channel model is established by using interleaving technique and RS-Turbo coding to improve GSM-R error control mode. The simulation results show that the adopted channel model can reduce such noise interference and reduce the system error rate.
