基于GSM-R标准的铁路无线收发系统设计

Design of Railway Wireless Transceiver and Transceiver System Based on GSM-R Standard

铁路无线通信是保障铁路正常运行的重要条件之一,提出了一种低成本多通道的铁路无线收发系统设计方案,介绍了系统的基本原理和框架,包括无线通信的编码与解码、调制与解调、交织与反交织、通信协议等内容。通过原型样机的试验,测试结果表明系统的无线信号传输效率高,误码率较低,可同时实现数据、图像和语音等信息的可靠安全传输,系统方案具有较强的实用性和通用性。

Railway wireless communication is one of the important conditions to ensure the normal operation of railways.This paper proposes a low-cost multi-channel design scheme for railway wireless transmission and transmission system,and introduces the basic principles and framework of the system,including the encoding and decoding of wireless communications,modulation and demodulation,interweaving and anti-interweaving,communication protocols and so on.Through the prototype test,the test results show that the system’s wireless signal transmission efficiency is high,the error rate is low,and it can realize the reliable and safe transmission of data,image and voice at the same time.The system scheme has strong practicality and universality.
