A method includes mapping a signal desired by at least one receiver to a projection area based at least on a functionality corresponding to one or more first radio frequency chains coupled to a plurality of first antennas; selecting precoding coefficients for at least one of one or more second radio frequency chains coupled to a plurality of second antennas to generate a signal point within the projection area; and compensating for a difference between the generated signal point and the signal desired by the at least one receiver using at least one of the first radio frequency chains, wherein the second radio frequency chains have a reduced functionality relative to the functionality of the first radio frequency chains, and wherein the first and second set of antennas are different.
