Abstract
A method for processing at least one polarization type of at least one wireless signal by a communication unit operably couplable to an antenna arrangement that comprises at least two orthogonally polarized antenna elements. The method comprises processing at least one signal radiated by at least one first antenna element of the antenna arrangement; and processing the at least one signal where processing comprises at least applying at least one digital complex scaling operation on the at least one signal radiated by at least one second antenna element of orthogonal polarization to the at least one first antenna element of the antenna arrangement thereby radiating at least one wireless signal of at least one non-native polarization type.

A method for processing at least one polarization type of at least one wireless signal by a communication unit operably couplable to an antenna arrangement that comprises at least two orthogonally polarized antenna elements, the method comprising:
- processing at least one signal as radiated by at least one first antenna element of the antenna arrangement;
- and
- processing the digitized format of the at least one signal by applying at least one digital complex scaling operation on the at least one signal as radiated by at least one second antenna element of orthogonal polarization to the at least one first antenna element of the antenna arrangement thereby radiating at least one wireless signal of at least one non-native polarization type;
- providing a digitized feedback signal to a calibration controller representative of a coupled signal at the antenna port;
- and
- performing at least one from a group of:
- phase correction, amplitude correction, latency correction, on the at least one signal.
A communication unit comprising:
- an interface for coupling to an antenna arrangement that comprises at least two orthogonally polarized antenna elements;

- provide a digitized feedback signal to a calibration controller representative of a coupled signal at the antenna port;
- and
- perform at least one from a group of:
- phase correction, amplitude correction, latency correction, on the at least one signal.
