The invention discloses a wireless communication link estimation method facing a high-speed railway linear community, and belongs to the technical field of wireless mobile communication. The method comprises the following steps: 1) a set of classification standard aiming at a high-speed railway characteristic spreading environment is put forward; 2) modeling is performed on large-scale path loss and shadow fading under various scenes, and a set of standardized spreading model library facing a high-speed railway is established; and 3) a coverage prediction method facing the railway linear community is put forward. The coverage range of the high-speed railway community is more accurately predicted under the premise of being without preliminary measurement so that a network arrangement scheme of the high-speed railway is optimized, base station spacing distance among communities is reasonably arranged and thus investment in high-speed railway wireless communication infrastructure is greatly reduced.
