ABSTRACT:
A method, system and apparatus for determining at least one relative characteristic of a transmit diversity transmitter based on at least one quality indicator based on signals received on the plurality of antennas. In some embodiments of the invention, the relative characteristic may be a relative power or amplitude ratio and/or a phase difference between the signals transmitted on the different antennas.
