Also, the shape of the plurality of antennas 310 shown in FIG. 3 is only an example, and in other embodiments, the plurality of antennas 310 may have various shapes (eg, rectangular, square, or circular).

According to an embodiment, the plurality of antennas 310 may be spaced apart from each other by a designated distance based on one axis.

As another example, the processor 120 may be electrically connected to the second antenna 312 through the second conductive connection member 322 . As another example, the processor 120 may be electrically connected to the third antenna 313 through the third conductive connection member 323 . In one embodiment, the conductive connection member 320 electrically connecting the processor 120 and the plurality of antennas 310 may be formed in various ways. For example, the conductive connection member 320 may be formed through a micro-strip. As another example, the conductive connection member 320 may be formed of a flexible printed circuit board (FPCB) and/or a FPCB type radio frequency cable (FRC).

According to an embodiment, the processor 120 may transmit and/or receive signals of a designated frequency band (eg, 3.1 to 10.2 GHz) using the plurality of antennas 310 . The designated frequency band may mean an ultra-wide band (UWB) band.

According to an embodiment, the processor 120 may perform positioning of an external device based on at least two antennas among the plurality of antennas 310 . For example, the processor 120 may identify a phase difference of arrival (PDoA) between signals based on signals received using the plurality of antennas 310, and calibrate the identified PDoA It can be converted to angle of arrival (AoA) (or angle of arrival) using a function. Also, the processor 120 may identify a relative direction in which the external device is located with respect to the electronic device 101 based on the converted AoA.

However, when the identified PDoA includes phase distortion, an AoA converted based on the phase-distorted PDoA may have an error, which may cause an error in positioning of the external device. For example, the PDoA identified due to the influence of a cover on the electronic device 101, a communication environment between the electronic device 101 and an external device, and/or a human body may include phase distortion. In this case, the phase-distorted PDoA may not be expressed as a sine function, but may have linearity, or may be expressed as a sine function whose maximum value and minimum value are not +1 and -1, respectively. As a result, when the electronic device 101 converts the PDoA including the phase distortion into the AoA using the arc sine function, the converted AoA may include a relatively high error and may cause a positioning error.

Hereinafter, in FIG. 4 , an operation of the processor 120 that converts a PDoA into an AoA by using a linear function when the PDoA is within a specified range will be described in order to reduce an error of the converted AoA due to phase distortion of the PDoA.

4 is a flowchart illustrating an operation of converting a PDoA into an AoA using a linear function when the PDoA is included in a first range according to an embodiment.

Referring to FIG. 4 , the processor 120 according to an embodiment may receive signals from an external device through the first antenna 311 and the second antenna 312 in operation 401 . For example, the processor 120 may receive a first signal from an external device through a first antenna 311 and receive a second signal from an external device through a second antenna 312 . In one embodiment, the first signal and the second signal are signals of a designated frequency band (eg, 3.1 to 10.2 GHz) and may correspond to a UWB frequency band. As another example, the first signal and the second signal may correspond to signals of a designated frequency band having a center frequency of about 6 to 8 GHz.

According to an embodiment, the processor 120 may identify the first PDoA of the first signal received through the first antenna 311 and the second signal received through the second antenna 312 in operation 403. . For example, the first PDoA may have a value equal to or greater than -180 degrees and equal to or less than +180 degrees.

According to an embodiment, the processor 120 may determine whether the first PDoA identified in operation 405 is within a first predefined range. For example, the first range may have a range of -180 degrees or more and +180 degrees or less. As another example, the first range may have a range of -180 degrees or more and -100 degrees or less and/or +100 degrees or more and +180 degrees or less.

According to an embodiment, if the first PDoA identified in operation 407 is within the first range, the processor 120 may convert the identified first PDoA into a first AoA using a first linear function. The first linear function may correspond to a calibration function. For example, the first linear function may be expressed as a linear function expression including coefficients A and B as shown in [Equation 1].

In [Equation 1], X is the value of the identified PDoA, and Y may mean the converted AoA value. In one embodiment, coefficient A and coefficient B may each have various values. For example, coefficient A and coefficient B may be determined based on the type of electronic device 101, whether or not a cover of the electronic device 101 is attached, and/or the communication environment of the electronic device 101. In one embodiment, information about the first linear function may be stored in the memory 130, and when the processor 120 converts the first PDoA into the first AoA, the information about the first linear function from the memory 130 may be stored. information can be obtained.

According to an embodiment, the processor 120 may perform positioning of the external device based on the first AoA converted in operation 409 . For example, the processor 120 may determine the relative direction in which the external device is located based on the first AoA.

4 has been described based on the first antenna 311 and the second antenna 312, but this is only an example, and the description described above in FIG. 4 is the first antenna 311 and the third antenna 313, or Substantially the same may be applied to the second antenna 312 and the third antenna 313 .

According to an embodiment, when the first range has a range of -180 degrees or more and +180 degrees or less, it may mean a case where the electronic device 101 converts PDoA into AoA using only the first linear function. . In an embodiment, the electronic device 101 converts PDoA into AoA using a first linear function compared to converting PDoA into AoA using an arcsine function, which is a nonlinear function, so that AoA according to phase distortion error can be reduced. For example, when the electronic device 101 converts a phase-distorted PDoA within a specified range (eg, -180 degrees to -100 degrees, +100 degrees to +180 degrees) into AoA using an arcsine function. AoA converted to may have a relatively high error. On the other hand, when the phase-distorted PDoA is converted into AoA using the first linear function according to an embodiment, even if the PDoA within the specified range is converted into AoA, the converted AoA may have a relatively small error. As a result, the electronic device 101 can prevent AoA from having a high error due to phase distortion by converting PDoA into AoA through the first linear function.

According to an embodiment, when the first range has a range of -180 degrees or more and -100 degrees or less and/or +100 degrees or more and +180 degrees or less, the electronic device 101 substantially operates a first linear function in the first range. It may mean converting the PDoA using , and converting the PDoA into the AoA through a separate calibration function (eg, a non-linear function) other than the first linear function in the range of more than -100 degrees and less than +100 degrees. Hereinafter, in FIG. 5 , an embodiment of converting PDoA into AoA through a separate calibration function (eg, non-linear function) other than the first linear function in a range of more than -100 degrees and less than 100 degrees will be described.

5 is a flowchart illustrating an operation of converting a PDoA into an AoA using a nonlinear function when the PDoA is included in a second range according to an embodiment.

Referring to FIG. 5 , if the first PDoA identified in operation 501 is within a predefined second range instead of the first range, the processor 120 according to an exemplary embodiment identifies the first PDoA using the first nonlinear function. may be converted into the second AoA. In one embodiment, the first nonlinear function may include various types of functions. For example, the first nonlinear function may include a trigonometric function (eg, an arcsine function) and/or an exponential function.

According to an embodiment, the processor 120 may perform positioning of the external device based on the second AoA converted in operation 503 . For example, the processor 120 may determine the relative direction in which the external device is located based on the second AoA.

Compared to the case of converting PDoA into AoA using only an arcsine function, the electronic device 101 according to an embodiment converts PDoA into AoA using a first linear function in a first range and converts it into AoA in a second range. In , an error of AoA due to phase distortion can be reduced by converting to AoA using a first nonlinear function. For example, when the electronic device 101 converts a phase-distorted PDoA within a specified range (eg, -180 degrees to -100 degrees, +100 degrees to +180 degrees) into AoA using an arcsine function. The converted AoA may have a relatively high error. On the other hand, the electronic device 101 according to an exemplary embodiment uses a first linear function in a first range (eg, -180 degrees to -100 degrees and/or +100 degrees to +180 degrees) to distort the phase. In the case of converting the converted PDoA into AoA, even if the PDoA within the designated range is converted into AoA, the converted AoA may have a relatively small error. As a result, the electronic device 101 can prevent the AoA from having a high error due to phase distortion by converting the PDoA into the AoA using the first linear function in the first range.

In addition, in the second range (eg, greater than -100 degrees and less than +100 degrees), when converting PDoA into AoA using the first nonlinear function, the error of the converted AoA is smaller than when converting the PDoA using the first linear function. can Therefore, when the electronic device 101 according to an embodiment converts the phase-distorted PDoA into AoA using the first nonlinear function in the second range (eg, greater than -100 degrees and less than +100 degrees), the converted AoA is relatively can have a small error. As a result, the electronic device 101 can convert the PDoA into the AoA using the first nonlinear function in the second range so that the AoA has a relatively small error due to the phase distortion.

Referring to FIG. 6B , when the PDoA graphs 610 shown in FIG. 6A are converted using an arc sine function, first AoA graphs 620 and PDoA graphs 610 are converted using a linear function. A case of second AoA graphs 630 is shown.

Comparing the first AoA graphs 620 and the second AoA graphs 630 according to an embodiment, the first AoA graphs 620 have a relatively third range compared to the second AoA graphs 630 . (eg, -90 degrees or more -50 degrees or less, and / or +50 degrees or more +90 degrees or less).

6C is a first error graph obtained by calculating errors of the first AoA graphs shown in FIG. 6B , a second error graph obtained by calculating errors of the second AoA graphs shown in FIG. 6B , and an error between PDoA graphs shown in FIG. 6A . It shows a third error graph in which .

Comparing the first error graph 641 and the second error graph 642 according to an embodiment, the converted AoA is within a third range (eg, -90 degrees or more -50 degrees or less, and/or +50 degrees or more). +90 degrees or less), it can be seen that the first error graph 641 has a relatively higher error value than the second error graph 642 . In addition, when the converted AoA is in the fourth range (eg, greater than -50 degrees and less than +50 degrees), it can be confirmed that the second error graph 642 has a relatively higher error value than the first error graph 641. there is.

As a result, the electronic device 101 uses a nonlinear function (eg, an arc sine function) as a calibration function in the third range (eg, -90 degrees or more and -50 degrees or less, and/or +50 degrees or more and +90 degrees or less). In the fourth range (eg, greater than -50 degrees and less than +50 degrees), an error of the converted AoA may be minimized or reduced by using a linear function as a calibration function.

According to an embodiment, the third range of the converted AoA (eg, -90 degrees or more and -50 degrees or less, and/or +50 degrees or more and +90 degrees or less) is the first range of the PDoA (eg, -180 degrees or more). -100 degrees or less, +100 degrees or more and +180 degrees or less). In an embodiment, the fourth range of converted AoA (eg, greater than -50 degrees and less than +50 degrees) may correspond to the second range of PDoA (eg, greater than -100 degrees and less than -100 degrees). Therefore, the electronic device 101 can reduce the AoA error by using a nonlinear function (eg, an arc sine function) as a calibration function in the first range and using a linear function as a calibration function in the second range.

For example, referring to the second graph, which is an enlarged view of the first part of the first graph, when the degree of phase distortion of the PDoA is 0 degrees, the first error graph of the AoA converted to a nonlinear function (eg, an arc sine function) ( 711) is shown. It can be seen from the first error graph 711 that the error value of AoA decreases as the ground truth (GT) value increases from 0 degree to 50 degree. In addition, it can be seen from the first error graph 711 that the AoA error value is minimum when the GT value is 50 degrees, and that the error value increases again as the GT value increases based on 50 degrees. Through this, when the degree of phase distortion of the PDoA is 0 degree, the electronic device 101 should determine the reference (or boundary value) of the first range corresponding to the linear function and the second range corresponding to the nonlinear function to be 50 degrees. It can be seen that the error of AoA due to PDoA phase distortion can be reduced.

In the case of 40 degrees, referring to the second error graph 712 of the AoA converted to a nonlinear function, it can be seen in the second error graph 712 that the error value of the AoA decreases as the GT value increases from 0 degrees to 45.5 degrees. there is. In addition, it can be seen from the second error graph 712 that the error value of AoA is minimum when the GT value is 45.5 degrees, and that the error value of AoA increases again as the GT value increases based on 45.5 degrees. Through this, the electronic device 101 determines the degree of phase distortion of the PDoA.

For another example, referring to the third graph, which is another enlarged view of the first part of the first graph, when the error of PDoA is 0 degrees, the first error graph converted to a nonlinear function (eg, an arc sine function) (711), and the error of PDoA

In the case of 20 degrees, a third error graph 713 converted to a nonlinear function is shown. In an embodiment, considering that the GT value at which the error value of the AoA of the first error graph 711 is the minimum is 50 degrees, the electronic device 101 responds to the linear function based on the GT value of 50 degrees. It can be seen that the error of the AoA due to the phase distortion of the PDoA can be minimized only when the criterion (or boundary value) of the first range corresponding to the nonlinear function and the reference (or boundary value) of the second range corresponding to the nonlinear function are determined to be 50 degrees.

For example, the first nonlinear function may correspond to [Equation 2] as follows.

Referring to [Equation 2], X and Y may respectively correspond to PDoA and AoA in order. A may correspond to a coefficient associated with a distance between the plurality of antennas 310 . B is a coefficient for reducing the AoA error and may vary depending on the type of electronic device 101 and/or the communication environment of the electronic device 101 . For example, A may correspond to 21 mm and B may correspond to 4 degrees.

The second AoA graph according to an embodiment can be referred to as a graph obtained when the processor 120 converts the PDoA into an AoA using a linear function when the identified PDoA has a phase distortion within a specified range. For example, a linear function may correspond to [Equation 3] as follows.

A and B are coefficients for reducing the AoA error and may vary depending on the type of electronic device 101 and/or the communication environment of the electronic device 101 . For example, A may correspond to 0.9 and B may correspond to 0 degrees.

Comparing the first AoA graph and the second AoA graph, when the AoA is in the third range (eg, -90 degrees to -50 degrees and/or +50 degrees to -90 degrees), the first AoA graph is It has a relatively high variance compared to the 2 AoA graph, and as a result, the first AoA graph has a relatively low linearity in the third range compared to the second AoA graph. In an embodiment, the third range of AoA (eg, -90 degrees or more and -50 degrees or less and/or +50 degrees or more and +90 degrees or less) is the PDoA's first range (eg, -180 degrees or more -100 degrees or less). and/or more than +100 degrees and less than +180 degrees).

A fourth AoA graph according to an embodiment may be referred to as a graph obtained when the processor 120 converts the PDoA into an AoA using a linear function when the identified PDoA has a phase distortion within a specified range.

Comparing the third AoA graph and the fourth AoA graph, when the AoA is part of the third range (eg, more than +50 degrees and less than -90 degrees), the first AoA graph has a relatively high variance compared to the second AoA graph. As a result, the third AoA graph has relatively low linearity in a part of the third range (eg, between +50 degrees and -90 degrees) compared to the fourth AoA graph.

In one example, the fifth range may partially overlap with the first range of the first PDoA and may have another range, or there may be no overlapping range.

According to another embodiment, if the identified second PDoA is included within the fifth range, the processor 120 may convert the identified second PDoA into a second AoA using a first linear function.

According to an embodiment, if the second PDoA identified in operation 1011 is within a predefined second range instead of the first range, the processor 120 converts the identified first PDoA into a second AoA using a first nonlinear function. can be converted For example, the second range may include a range of greater than -100 degrees and less than +100 degrees.

The sixth range may be different from the second range. For example, the sixth range partially overlaps the second range (eg, greater than -100 degrees and less than +100 degrees), but may correspond to a different range. For another example, the sixth range may not entirely overlap with the second range and may correspond to another range.
