介绍了在郑州至西安（ZX）高速铁路和北京至天津（BT）高速铁路上进行的高速条件下宽带信道特性的测量工作。激励信号采用宽带码分多址（WCDMA），带宽为3.84 MHz，从沿着铁路的基站发射，由列车内的ROHDE &施瓦茨公司的TSCDMA接收。选取平原、U形切割、台站和丘陵地形等不同场景进行测量，提取了信道多径特性参数，并进行了分析和简要报告。这些结果对未来高速铁路无线通信系统的设计具有一定的参考价值。
The paper describes the measurement campaigns for the broadband channel properties under the high- speed condition, which have been carried out on Zhengzhou to Xi'an (ZX) High-Speed Railway and Beijing to Tianjin (BT) High-Speed Railway. WCDMA with the bandwidth of 3.84MHz is employed as the excitation signal that is transmitted from the base station along the railway and received by the TSMQ by ROHDE & SCHWARZ inside the train. Different scenarios including plain, U-shape cutting, station and hilly terrain are chosen in the measurements and the parameters about the channel multipath properties are extracted, analyzed and briefly reported here. These results are informative for the system designers in the future wireless communication of High-Speed Railway.
