1. A method of processing information prior to emission thereof on a multi-antenna emission, comprising preceding said information and scaling said precoded information prior to emission thereof, the precoding comprising applying a perturbation to said information before transmission, said perturbation being expressible as a perturbation vector, wherein said perturbation vector is selected by defining a lattice representing possible identities of information to be sent, defining a reduced lattice from said lattice, selecting a first candidate perturbation vector from said reduced lattice, selecting further candidate perturbation vectors, transforming said candidate perturbation vectors from expression in said reduced lattice into expression in said defined lattice, selecting one of said transformed candidate identities as perturbation to be applied, and said scaling comprising scaling said information after perturbation on the basis of a transmitted power constraint, wherein said selecting of one of said transformed candidate identities is performed on the basis of a scaling factor employed in said scaling.
