<P>PROBLEM TO BE SOLVED: To provide a method capable of improving performance of vector perturbation nonlinear precoding techniques regarding multiple-input multiple-output (MIMO). Ž<P>SOLUTION: Precoding information prior to MIMO transmission is described, comprising determining a suitable precoding perturbation. The perturbation is determined by assembling a list of candidate perturbations in reduced lattice space, transforming them back into information lattice space and determining which candidate precoder perturbation is most suitable for a given performance criterion.
