Abstract
Matrices to be used for the random orthogonal transformation of blocks of data in a transmission chain are generated. A square matrix with orthogonal column vectors and orthogonal row vectors is divided to create M matrices. The number of rows of each of these matrices is equal to M*n, where n is the number of columns of each of the matrices and M is an integer larger than one. Each of the M matrices is allocated to a transmitter in a transmission chain or, alternatively, a plurality of the M matrices are allocated to one base station of a wireless transmission system.
