Method and device for constructing composite small-scale radio channel model of high-speed rail

The invention provides a method and device for constructing a composite small-scale radio channel model of a high-speed rail, relating to the radio communication field. The method comprises the following steps of: 1, constructing typical scene sub-channels according to various types of scenes experienced by the high-speed rail; 2, according to the high-speed rail to be tested, selecting corresponding composite small-scale sub-channel types and the typical scene sub-channels; 3, sequencing all selected typical scene sub-channels according to requirements; confirming the duration time of each typical scene sub-channel; and 4, combining the typical scene sub-channel types according to the determined arrangement way and the relative duration time; and obtaining the composite small-scale radio channel model of the high-speed rail. The device comprises a sub-channel constructor, a type selector, a sequencing and time confirmer and a combiner. By means of the method and the device disclosed by the invention, the required complete comprehensive radio channel model of the high-speed rail can be obtained, the radio channel of the high-speed rail can be depicted accurately and comprehensively, and the accuracy for test and simulation can be improved.
