| Abstract: | 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. |
