A method for processing at least one polarisation type of at least one wireless signal by a communication unit operably couplable to an antenna arrangement that comprises at least two orthogonally polarised 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 polarisation 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 polarisation type. The method further comprises providing a digitised feedback signal to a calibration controller representative of a coupled signal at an at least one antenna port of the antenna arrangement; and performing at least one from a group consisting of: phase correction, amplitude correction, latency correction, on the at least one signal radiated by the at least one antenna port to regulate at least, the at least one non-native polarisation type.
