Claim:
1. A wireless communication system comprising: a transmitter operable to transmit a source signal, the transmitter having one or more transmitting antennae, wherein the source signal is multiplied by a channel matrix before being transmitted by the transmitter; and a receiver operable to receive a received signal, the receiver having one or more receiving antennae; wherein the transmitter comprises a calculating unit for calculating a lattice reduction matrix for transforming the channel matrix into a form in which rows and columns are more orthogonal, the transmitter being operable to obtain a decomposed representation of the lattice reduction matrix and to transmit said decomposed representation of the lattice reduction matrix to the receiver, wherein the decomposed representation of the lattice matrix is represented by fewer bits than the lattice reduction matrix, and wherein the receiver is further operable to receive the decomposed representation of the lattice reduction matrix, to reconstruct the lattice reduction matrix therefrom, and to obtain an estimate of the source signal utilizing the lattice reduction matrix.
