Abstract
AbstractHigh‐speed railway (HSR) is becoming one of the most effective and important transportation modes. To ensure the safety of HSR, a stable communication system is necessary. The understanding of propagation characteristics of radio channel is important for HSR communication system design. In this paper, a wideband measurement in suburban HSR scenarios at 460 MHz is presented. Some typical channel parameters such as the large‐scale fading, Ricean factor, power‐delay profile, and root‐mean‐square delay spread are extracted from the measurement data. The different distributions of small‐scale fading are also compared. The relationships between the channel parameters and the distance of transmitter (base station) and receiver are also explored. The results could provide a reference for the design and evaluation of HSR communication network, especially for the Long‐Term‐Evolution (LTE)‐railway system.
