Abstract

Abstract: High‐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 K 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. Key Points: Measurements in the high‐speed railway environment at the LTE‐R band are conducted in China Channel characterization including both of large‐scale parameters and small‐scale parameters are presented Distance dependency of channel parameters and correlation characteristics are investigated
