Claim 6:
7. The method according to claim 3, wherein the first amplitude information is determined based on an average value of amplitude information of at least two elements of Gu, and the second amplitude information is determined based on an average value of amplitude information of at least two elements of Gd; or
the first amplitude information is determined based on an average value of amplitude information of at least two elements of a matrix (W2,u) corresponding to Gu, and the second amplitude information is determined based on an average value of amplitude information of at least two elements of a matrix (W2,d) corresponding to 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 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}.
