Abstract: This application provides example signal processing methods, media, and apparatuses. One example method includes obtaining a scattering parameter matrix of passive echoes in an antenna system by a network device. The m virtual user directions are determined by the network device based on the scattering parameter matrix of the passive echoes, where the m virtual user directions are m directions in which total signal strength of the passive echoes is highest, and m is a positive integer. A target beam is formed based on n real user directions and the m virtual user directions, where one or more nulls of the target beam are aligned with the m virtual user directions, n is a positive integer, and n+m≤k.

Abstract: A data integration method and apparatus, where the method includes sampling a first data source (A) at least twice to obtain a first sample data source (a) and a second sample data source (a′), separately calculating an index of each attribute field of the A, a second data source (B), the a, and the a′, determining a decision value of an attribute field Xi of the A according to a difference degree between an index of an attribute field Xi of the a and an index of each attribute field Xi of the a′, and mapping, to the attribute field Xi of the first data source, an attribute field that is of the B and whose index and the attribute field Xi of the A have a difference degree less than the decision value.
