Application: Communication device and method of operation (Patent ID: US20230417865A1)

The patent filed by NXP Semiconductors NV describes a communication device that utilizes multiple antennas to receive ultra-wideband signals and determine the angle of arrival (AoA) of these signals based on the phase difference of arrival (PDoA). Additionally, the device includes a polarization angle estimation unit to estimate the polarization angle of the signal, which is then used in conjunction with the PDoA to determine the AoA accurately. The method of operating this communication device involves receiving the ultra-wideband signal, estimating the polarization angle, and using the PDoA and polarization angle to determine the AoA effectively.

Furthermore, the communication device's antennas have different polarizations, allowing for the estimation of the polarization angle by measuring the signal strength ratio between antennas. The device's processing unit uses the estimated polarization angle to select a mapping between PDoAs and AoAs, enhancing the accuracy of determining the signal's AoA. The method can be implemented as a computer program stored in a non-transitory computer-readable medium, enabling communication devices to carry out the described operations efficiently.
