ABSTRACT:
A first reference signal and a first data signal are transmitted from a first antenna of a base station and a second reference signal and a second data signal are transmitted from a second antenna of the base station. The first and second antennas are difference antennas. The first and second reference signals having different codes and the first and second data signals having different codes. The received first and second reference signals are combined using an adaptive algorithm producing adaptive algorithm weights. Data from the first and second data signals is recovered by combining the first and second data signal in response to adaptive algorithm weights.
