An apparatus and method for adjusting transmission phasing in a point-to-point communication link is disclosed. The relative phases of the transmissions from each antenna are adjusted before transmission to give optimum gain when received by two or more antenna elements and a signal combining element. The signal includes a data component, consisting of a subset of the subcarriers modulated with the input data, which is common to transmissions from all antenna elements; and a phase reference component consisting of a subset of the subcarriers that are modulated with a predetermined phase. The signal combining element is operable to receive the components and extract phase information. A phase adjustment signaling device compares extracted phase information and signals the plurality of transmitting antenna elements to adjust the relative transmission phasing between the signals transmitted from a plurality of transmitting antenna elements to permit a receiver to receive the transmitted signals with a desired phase relationship.
