Abstract
An orthogonal code matrix generation method includes: establishing an N×N orthogonal code matrix, wherein an inner product of every two rows of the orthogonal code matrix is 0, and each column of the orthogonal code matrix has a summation of elements equal to a same value, wherein N is a power of 4; and using the N×N orthogonal code matrix as a basic unit to establish a target orthogonal code matrix. An orthogonal code matrix generation circuit includes: an N×N orthogonal code matrix generator, arranged for establishing an N×N orthogonal code matrix, wherein an inner product of every two rows of the orthogonal code matrix is 0, each column of the orthogonal code matrix has a summation of elements equal to a same value; and a target orthogonal code matrix generator, arranged for using the N×N orthogonal code matrix as a basic unit to establish a target orthogonal code matrix.
