A data compression process is described, for compressing channel state information to be fed back to a transmitter. The process involves arranging the data as a matrix comprising a number of orthonormal vectors derived from a channel matrix, determining a singular value decomposition of a subset of the orthonormal matrix to generate matrices respectively of left and right singular vectors, the number of vectors in the subset being equal to the order of the vectors, and right multiplying the remainder orthonormal vectors not included in the singular value decomposition by a matrix product of the matrix of right singular vectors and the matrix of left singular vectors to generate a matrix of compressed data.
