Abstract: A preprocessing arrangement is configured for installation in a multiple-antenna communication system, e.g. a MI-MO-enabled device, to improve internal data transfer of the system. The arrangement is interposed between an antenna array and a computer device. In operation, the arrangement obtains (301) a diagonal matrix W of multiplicator values, the diagonal matrix W being given by H=WAX, wherein H is a channel transmission matrix for the system, A is a predefined filter matrix, and X is a matrix that depends on H. The arrangement further extracts (302) an input vector Y of signal values from the antenna array, generates (303) an output vector ? of output values by forming AHWHY, wherein superscript indicates Hermitian transpose, and provides the output values in the output vector ? to the computer device. By providing the output vector ?, the number of signal values to be received and jointly processed by the computer device is reduced relative to the number of antennas in the antenna array.
