Claim 18:
19. The apparatus according to claim 16, wherein the first amplitude information is determined based on an element whose amplitude information has a largest value in at least one column of elements of a matrix (W2,u) corresponding to Gu; and
the second amplitude information comprises n sub-elements, an ith sub-element in the n sub-elements is determined based on an element whose amplitude information has a largest value in N elements in an ith column in n columns of a matrix (W2,d) corresponding to Gdn is a positive integer, and i∈{1, 2, . . . , n}, wherein
GuT(lu)=W1×W2,u(lu), GdT(ld)=W1×W2,d(ld), XT represents transposition of a matrix X, X(lu) represents an lu column of the matrix X, X(ld) represents an ld 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}.
