摘要： In accordance with a first aspect of the present disclosure, a communication device (500) is provided, comprising: a plurality of antennas (502, 504) configured to receive an ultra-wideband signal; a processing unit (508) 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; a polarization angle estimation unit (506) 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. In accordance with a second aspect of the present disclosure, a corresponding method of operating a communication device is conceived. In accordance with a third aspect of the present disclosure, a computer program is provided for carrying out said method.

摘要： In accordance with a first aspect of the present disclosure, a communication system is provided, comprising: a plurality of communication nodes which are operatively coupled to each other, wherein each of said communication nodes comprises a first radio frequency (RF) communication unit configured to perform ranging sessions with an external communication device; a controller configured to create a logical subset of said communication nodes based on an indication of a channel quality between the communication nodes and the external communication device, wherein said indication of the channel quality has been obtained using a second RF communication unit comprised in each of said communication nodes; the controller further being configured to cause that only the communication nodes included in said logical subset perform said ranging sessions with the external communication device. In accordance with a second aspect of the present disclosure, a corresponding method of operating a communication system is conceived. In accordance with a third aspect of the present disclosure, a computer program is provided for carrying out said method.

摘要： In accordance with a first aspect of the present disclosure, a localization system is provided, comprising: a plurality of ultra-wideband (UWB) communication nodes; a plurality of antennas, each one of said antennas being included in one of said UWB communication nodes; an antenna selection unit configured to select a subset of said antennas for use in ranging operations that output a position estimate of an external device; wherein the antenna selection unit is configured to select said subset in dependence on at least one previous ranging operation. In accordance with a second aspect of the present disclosure, a corresponding method of operating a localization system is conceived. In accordance with a third aspect of the present disclosure, a computer program is provided, comprising computer-executable instructions that, when executed by a localization system, cause said localization system to carry out a method of the kind set forth.
