Abstract

The Japanese National Railways has stretched its bullet train system to the north in 1982 and built a new type train radio system for it. The new system utilizes Leaky Coaxial Cable, a wired-wireless technique which offers many services such as train operation dispatching, passenger dispatching, public telephone, train status monitoring and so on. Taking advantage of sufficient receiving level from LCX, the system was designed to have 40 dB signal to noise ratio at more than 99 percent areas for voice communication channels and less than 10-4bit error rate at almost all areas for 1200 bit/s FSK data communication channel. Measurement after construction of the railway lines has verified that the intended quality is attained for both voice and data communication. Block error rate for triple transmission of same data also proved to be less than 10-3in the measurement. In this system, stable receiving level for relatively small power and efficient use of frequency resources are realized through isolat ion between zones and narrow dynamic range of LCX.

使用泄漏同轴电缆的列车无线电系统
1982年,日本国家铁路公司将子弹头列车系统向北延伸,并为其建造了新型列车无线电系统。该系统采用泄漏同轴电缆这一有线无线技术,可提供列车运行调度、旅客调度、公用电话、列车状态监控等多种服务。利用LCX足够的接收电平,系统设计为语音通信信道在99%以上区域的信噪比为40 dB, 1200比特/秒FSK数据通信信道在几乎所有区域的误码率小于10-4bit。铁路线路建成后的测量证实,语音和数据通信都达到了预期的质量。在测量中,同一数据三次传输的分组误差率也小于10-3。在该系统中,通过区域间隔离和LCX的窄动态范围,实现了相对小功率的稳定接收电平和频率资源的有效利用。
