Description

Electronic equipment

technical field

The present application relates to the field of communication technologies, and in particular, to an electronic device.

Background technique

At present, Ultra Wide Band (UWB) technology is a short-distance wireless communication method, and its transmission distance is usually within 10m, using a bandwidth of more than 1GHz. UWB technology does not use a sinusoidal carrier, but transmits data by using a non-sinusoidal narrow pulse of nanosecond to microsecond level, so it occupies a wide spectrum range. UWB technology has the advantages of low system complexity, low power spectral density of transmitted signals, insensitivity to channel fading, low interception capability, and high positioning accuracy, and is suitable for high-speed, short-range wireless personal communication. Angle of Arrival (AOA) is a key parameter in UWB technology. For the antenna assembly, the angle of arrival (Angle of Arrival, AOA) is usually obtained based on the phase difference (Phase Difference of Arrival, PDOA) of the electromagnetic wave signal reaching two antennas in the electronic device. In the related art, since the user is using the electronic device, the different postures of the electronic device will lead to different PDOA measurement values, that is, the PDOA does not converge. The non-convergence of PDOA will lead to inaccurate results when using PDOA for AOA calculation. Inaccurate AOA results may cause problems such as inaccurate positioning results when using the antenna in the electronic device for positioning.
