Claim 3:
4. The method according to claim 3, wherein the first amplitude information is determined based on any one of the following elements:
an element whose amplitude information has a largest value in at least one row of elements of Gu, an element whose amplitude information has a largest value in at least one column of elements of a matrix (W2,u) corresponding to Gu, a singular value whose amplitude information has a largest value in at least one singular value of Gu, or an eigenvalue whose amplitude information has a largest value in at least one eigenvalue of Gu; and/or
the second amplitude information is determined based on any one of the following elements:
an element whose amplitude information has a largest value in at least one row of elements of Gd, an element whose amplitude information has a largest value in at least one column of elements of a matrix (W2,d) corresponding to Gd, an eigenvalue whose amplitude information has a largest value in at least one eigenvalue of Gd, or a singular value whose amplitude information has a largest value in at least one singular value of Gd, wherein
GuT(lu)=W1×W2,u(lu), GdT(ld)=W1×W2,d(ld), XT represents transposition of a matrix (X), X(lu) represents an luth column of the matrix X, X(ld) represents an ldth column of X, W1 is an M*N matrix, W2,u is an N*x matrix, W2,d is an N*m matrix, N is a positive integer, lu∈{1, 2, . . . , x}, and ld∈{1, 2, . . . , m}.
