Claim 4:
5. The method according to claim 1, wherein decomposing the channel matrix into the product of the matrix Q, the matrix R, and the matrix PH comprises:
performing singular value decomposition (SVD) on the channel matrix, to decompose the channel matrix into a product of a matrix U, a matrix Σ, and a matrix VH, wherein the matrix VH is a conjugate transpose matrix of a matrix V, both the matrix U and the matrix V are unitary matrices, and the matrix Σ is a diagonal matrix; and
transforming the matrix U, the matrix Σ, and the matrix VH to obtain the matrix Q, the matrix R, and the matrix PH.
