Systems/methods of using dual polarization antennas in cellular communications

A first device that is configured to perform operations comprising:

• receiving from a second device a first signal on a first polarization;
• the first signal comprising a first dependency on a first waveform and on a second waveform that are radiated by an antenna system of said second device;
• concurrently in time and co-frequency with said receiving from a second device a first signal on a first polarization, receiving from the second device a second signal on a second polarization;
• the second signal comprising a second dependency on the first waveform and on the second waveform that are radiated by the antenna system of said second device;
• jointly processing the first signal and the second signal using at least one complex valued coefficient;
• and
• forming a third signal and a fourth signal responsive to said jointly processing;
• wherein the third signal comprises a level of the second waveform that is less than a level of the second waveform that is included in the first signal;
• and
• wherein the fourth signal comprises a level of the first waveform that is less than a level of the first waveform that is included in the second signal.
