Communication device and method of operation

A communication device, comprising:

• a plurality of antennas configured to receive an ultra-wideband signal;
• a processing unit configured to determine an angle of arrival (AoA) of the ultra-wideband signal, wherein said AoA is based on a phase difference of arrival (PDoA) derived from the ultra-wideband signal;
• and
• a polarization angle estimation unit configured to estimate a polarization angle of the ultra-wideband signal,
• wherein the processing unit is further configured to determine the AoA of the ultra-wideband signal using the polarization angle estimated by the polarization angle estimation unit.

A method of operating a communication device, the communication device comprising a plurality of antennas, a processing unit and a polarization angle estimation unit, the method comprising:

• receiving, by the antennas, an ultra-wideband signal;
• estimating, by the polarization angle estimation unit, a polarization angle of the ultra-wideband signal;
• and
• determining, by the processing unit, an angle of arrival (AoA) of the ultra-wideband signal using a phase difference of arrival (PDoA) derived from the ultra-wideband signal and the polarization angle estimated by the polarization angle estimation unit.
