Transmitting a data signal employing a digital beamforming technique including determining a first phase offset in response to a first transmitted signal received at a first antenna and a second phase offset in response to a second transmitted signal received at the first antenna, determining a third phase offset in response to the first transmitted signal received at a second antenna and a fourth phase offset in response to the second transmitted signal received at the second antenna, generating a first correction weight in response to an average of the first phase offset and the third phase offset, generating a second correction weight in response to an average of the second phase offset and the fourth phase offset, and transmitting the first correction weight to the first transmitter and the second correction weight to the second transmitter.
