Title:
BLIND MULTIPATH IDENTIFICATION METHOD AND SYSTEM FOR MIMO SYSTEM BASED ON WEIGHTED INTEGRATED CLUSTERING ALGORITHM
Document Type and Number:
WIPO Patent Application WO/2020/248092
Kind Code:
A1
Abstract:
The present disclosure relates to a blind multipath identification method for an MIMO system based on a weighted integrated clustering algorithm. The method comprises: multiple users send communication request signals to a base station; the users adjust the transmission power of the users on the basis of response signals fed back by the base station, so that the base station allows the communication requests of the users; the users send information signals to the base station; the base station generates the input signals of basic clustering algorithms on the basis of the separated information signals, and on the basis of the output result of each basic clustering algorithm, the base station adaptively adjusts the weight of the output result of each basic clustering algorithm by means of a weighted integrated clustering algorithm, and identifies the paths of the information signals of the users according to the outputs of the weighted integrated clustering algorithm; the base station performs the maximum-ratio combining of the users and decodes the information signal of each user. According to the present disclosure, multipath identification can be stably and effectively performed on the basis of a weighted integrated clustering algorithm.
