The invention provides a method for clustering multipath components in a wireless time-varying channel. The method comprises the steps of: using a variation of MPCs (Multipath Components) in the wireless time-varying channel in an angle domain and a time delay domain as a markoff process, calculating state transition probabilities of the MPCs between continuous frames in the wireless time-varying channel on the basis of Euclidean distances between the MPCs, and establishing a state transition probability matrix of the MPCs between the continuous frames; and comparing each state transition probability in the state transition probability matrix with a preset threshold, and according to comparison results, carrying out clustering on the MPCs in the frames of the wireless time-varying channel. The algorithm provided by the invention considers the time-varying characteristics of the MPCs, implements completion of the clustering operation when tracking, can sufficiently show the time-varying characteristics of clusters, and meets the channel modeling requirement facing a cluster structure in the wireless communication field in future.
