[0039] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0040] This disclosure provides a data transmission method 10, which can be used in mobile terminals such as mobile phones and tablets. The mobile terminal is equipped with a radar wave sensor, which can transmit data in the form of radar waves and can also receive radar waves, wherein the radar waves can be a type of electromagnetic wave. See also Figure 1 The data transmission method 10 includes steps S11-S12, which are described in detail below:

[0041] Step S11: Encode the data file to be sent to obtain an encoded file.

[0042] The user determines the data file to be sent, encodes it, and creates an encoded file that can be transmitted via radar waves. The encoding method can be uniformly set on the mobile terminal, with the encoding and decoding methods corresponding to ensure file transmission. The encoding method can be set according to the form of the radar wave, such as encoding based on the up-sweep and down-sweep frequency bands in a linear frequency modulated signal. Alternatively, the data file can be encoded into a 0 / 1 encoded file before being transmitted via radar waves. The decoding method is set accordingly to the encoding method.

[0043] Step S12: The encoded file is modulated and transmitted as radar waves using a radar wave sensor.

[0044] After encoding, the encoded file can be transmitted as radar waves via a radar wave sensor. Radar waves can propagate over a wide area, and can be received by other mobile terminals equipped with radar wave sensors within that range. No network connection, Bluetooth pairing, or other authentication processes are required, enabling convenient and quick public file sharing.

[0045] In one embodiment, see Figure 2 The data transmission method 10 further includes step S13, determining the modulation scheme of the radar wave, wherein the modulation scheme includes at least one of the following: frequency modulation, amplitude modulation, or phase modulation; step S12 may include modulating the encoded file based on the modulation scheme and transmitting it as a radar wave. The modulation scheme determines the frequency, amplitude, and other forms of the radar wave, and the transmitting end and receiving end need to use the same modulation scheme to achieve data transmission. The modulation scheme can be uniformly set by default in the mobile terminal, or it can be determined based on the user's settings. In this embodiment, the modulation scheme can be set accordingly to achieve personalized communication matching in different scenarios and to achieve data transmission between mobile terminals using the same modulation scheme.

[0046] In one embodiment, the radar wave is a linear frequency modulation (LFM) signal, that is, a signal whose instantaneous frequency changes linearly with time, which can ensure transmission distance and improve resolution. Encoding can be performed according to the linear frequency modulation method.

[0047] Based on the same inventive concept, this disclosure also provides a data receiving method 20, which is also applied to a mobile terminal equipped with a radar wave sensor. See [link to relevant documentation]. Figure 3The data receiving method 20 includes: step S21, receiving radar waves through a radar wave sensor and demodulating them to obtain an encoded file; step S22, decoding the encoded file to obtain a data file. In contrast to the data sending method 10, the mobile terminal can receive radar waves through a radar wave sensor, demodulate the radar waves to obtain an encoded file through demodulation corresponding to modulation, and then further decode it to restore the original transmitted data file.

[0048] In one embodiment, such as Figure 4 As shown, the data receiving method 20 further includes: step S23, determining the modulation scheme of the radar wave, wherein the modulation scheme includes at least one of the following: frequency modulation, amplitude modulation, or phase modulation; step S21 may further include: demodulating the radar wave based on the modulation scheme to obtain an encoded file. Corresponding to some of the embodiments described above, the received radar wave can be demodulated into a correct encoded file based on a pre-determined modulation scheme, so that the modulation scheme corresponding to the modulation at the transmitting end can be used for demodulation.

[0049] Based on the same inventive concept and according to the characteristics of radar waves, this disclosure also provides a data transmission method 30, applied to a data transmission system. The data transmission system includes a first mobile terminal and one or more second mobile terminals, wherein both the first and second mobile terminals are equipped with radar wave sensors. Figure 5 This diagram illustrates a method of transmitting data files from a first mobile terminal to multiple second mobile terminals via radar waves. Figure 6 As shown, the data transmission method 30 includes:

[0050] Step S31: The first mobile terminal encodes the data file to be sent to obtain an encoded file;

[0051] Step S32: The first mobile terminal modulates the encoded file using a radar wave sensor and transmits it as a radar wave.

[0052] Step S33: One or more second mobile terminals receive radar waves through the radar wave sensor of the second mobile terminal and demodulate to obtain the encoded file;

[0053] In step S34, one or more second mobile terminals decode the encoded file to obtain a data file.

[0054] In one embodiment, the data transmission method 30 may further include determining the modulation scheme of the radar wave, wherein the modulation scheme includes at least one of the following: frequency modulation, amplitude modulation, or phase modulation. By uniformly setting the modulation scheme of mobile terminals in the data transmission system, file transmission can be guaranteed, and different modulation schemes can be used for transmission in different scenarios, thus ensuring security.

[0055] Radar waves can be transmitted over a wide area. Based on a mobile terminal, a radar wave can be emitted, and other mobile terminals within the transmission range can receive it through their own radar wave sensors. This makes it convenient to share public files in situations such as conferences and lectures.

[0056] Based on the same inventive concept, this disclosure also provides a mobile terminal 100, such as... Figure 7 As shown, the mobile terminal 100 is equipped with a radar wave sensor 110.

The mobile terminal 100 can act as a radar wave transmitter to send data to other mobile terminals, or as a receiver to receive data sent by other mobile terminals.

[0057] In one embodiment, the mobile terminal 100 is equipped with two radar wave sensors 110, which are respectively disposed on the front and rear sides of the mobile terminal 100. Radar waves have a certain directionality, and in some cases, due to limitations in transmission distance and power, their penetration through obstacles is poor. Therefore, by distributing radar wave sensors 110 on the front and rear sides of the mobile terminal 100, the success rate of receiving radar waves can be improved, and radar waves can be transmitted simultaneously in both directions.

The data transmission device 200 includes: an encoding unit 210 for encoding a data file to be transmitted to obtain an encoded file; and a transmission unit 220 for modulating the encoded file through the radar wave sensor and transmitting it in the form of radar waves.

The data receiving device includes: a receiving unit 310, which is used to receive radar waves through the radar wave sensor and demodulate them to obtain an encoded file; and a decoding unit 320, which is used to decode the encoded file to obtain a data file.
