wherein an mth element from top to bottom in a column in which d is located indicates a row weight of row m in the third matrix, an nth element (a, b) from left to right in row m in the third matrix indicates that a cyclic shift coefficient of a cyclic shift matrix in row m and column (a+n) in the third matrix is b, all remaining locations in the third matrix are all-zero matrices, n∈{1, 2, 3, 4, 5, 6, 7}, and m, a, and b are all positive integers.
