The embodiment of the invention provides an antenna determination method, wherein a mobile terminal can obtain M first quality parameters and M second quality parameters, and determine M corresponding relations according to the M first quality parameters and the M second quality parameters (one corresponding relation is a corresponding relation between one frequency point of M frequency points and one antenna, and the antenna is the antenna corresponding to the largest quality parameter of the first quality parameters and the second quality parameters). The mobile terminal can determine M corresponding relations according to the M first quality parameters and the M second quality parameters, one corresponding relation is the corresponding relation between one frequency point of the M frequency points and one antenna, and the antenna is the antenna corresponding to the largest quality parameter of the first quality parameters and the second quality parameters, so that the mobile terminal can determine the antenna with better performance corresponding to each frequency point of the M frequency points, and can receive signals by adopting the antenna with better performance corresponding to each frequency point, thereby avoiding the problem of interference among a plurality of FM signals received by adopting one antenna on a plurality of frequency points, and improving the quality of the FM signals received on each frequency point.
Optionally, in this embodiment of the present invention, as shown in fig. 6 in combination with fig. 2, after step 202, the method for determining an antenna provided in this embodiment of the present invention may further include the following steps 301 to 303.
In the embodiment of the present invention, after the mobile terminal determines the M corresponding relationships, the M corresponding relationships may be displayed on an interface of the mobile terminal, so as to prompt an antenna corresponding to the FM signal of each frequency point to a user.
Optionally, in the embodiment of the present invention, the mobile terminal may display the M corresponding relationships on an interface of the mobile terminal in a form of a list.
In an embodiment of the present invention, the target corresponding relationship is a corresponding relationship among M corresponding relationships.
In the embodiment of the present invention, a user may select at least one corresponding relationship (i.e., a target corresponding relationship) from the M corresponding relationships according to a use requirement (e.g., a frequency point of a desired FM signal).
For example, in combination with table 1, the mobile terminal may display 4 corresponding relationships, that is, corresponding relationship 1 to corresponding relationship 4, on an interface of the mobile terminal, and if the frequency point of the FM signal required by the user is frequency point 2, the user may perform the first input on corresponding relationship 2 corresponding to frequency point 2.
It can be understood that, when performing FM channel search, the mobile terminal may search for an FM signal through the antenna corresponding to the target correspondence at the frequency point corresponding to the target correspondence.
For example, it is assumed that the target correspondence is correspondence 2, and the correspondence 2 is correspondence between the frequency point 2 and the second antenna. The mobile terminal may receive the FM signal through the second antenna corresponding to the correspondence relationship 2 at the frequency point 2 corresponding to the correspondence relationship 2.
In the embodiment of the invention, because the mobile terminal can receive the FM signal through the antenna corresponding to the target corresponding relation on the frequency point corresponding to the target corresponding relation according to the first input of the user, and the antenna corresponding to the target corresponding relation is determined by the mobile terminal according to the quality parameter of the FM signal received on the frequency point corresponding to the target corresponding relation, the problem that the FM signal received by the mobile terminal is interfered can be avoided, namely, the problem of noise generated during FM channel searching can be avoided, and the quality of the received FM signal during FM channel searching can be improved.
