DATA PROCESSING METHOD AND APPARATUS

Provided in the present application are a data processing method and apparatus. The method comprises: obtaining a reference signal which is fed back by a second communication apparatus; obtaining HC on the basis of the reference signal, wherein HC is a matrix with a dimension of M×K, where M represents the number of antennas of a first communication apparatus, K represents the number of antennas of the second communication apparatus; and HC satisfies: HC = H1 TH2, where H1 is a matrix with a dimension of M×K, H2 is a diagonal matrix with a dimension of K×K, and a diagonal vector is α＝[α1, α2, ... αK]; pre-coding HC to obtain WC, wherein WC is a matrix with a dimension of M×K; obtaining a first received energy vector b = [b1, b2, ... bK], which is fed back by the second communication apparatus; obtaining a second received energy vector a = [a1, a2, ... aK] according to HC and WC; and obtaining α and H2 according to a and b, and obtaining H1 according to H2 and HC, wherein H 1 is used for channel estimation.
