BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The present invention will be further described below in conjunction with the accompanying drawings.

[0058] Figure 1 It is a flow chart of a wireless communication method based on a radio frequency transceiver circuit of the present invention. DETAILED DESCRIPTION

[0059] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] See also Figure 1 As shown, the present invention is a wireless communication method based on a radio frequency transceiver circuit. Figure 1The present invention is a flow chart of a wireless communication method based on a radio frequency transceiver circuit. The radio frequency transceiver circuit may include a wireless signal transceiver, a multi-stage array antenna and a power amplifier, one end of the power amplifier is connected to the wireless signal transceiver, and the other end is connected to the multi-stage array antenna.

[0061] A wireless signal transceiver is an electronic device used to transmit and receive wireless signals, supporting signal modulation, demodulation, encoding and decoding. In the transmission mode, the wireless signal transceiver can convert digital data packets into radio frequency signals suitable for transmission. In the receiving mode, the received radio frequency signal is demodulated into digital data.

[0062] A power amplifier is used to increase the power of a signal to achieve the strength required for long-distance transmission. A power amplifier is used to ensure that the signal does not become weak due to long transmission distances, and to improve the transmission quality and coverage of the signal.

[0063] A multi-level array antenna is a combined system consisting of multiple antenna units that transmits and receives signals through precise phase and amplitude control. Multi-level array antennas can perform beam forming and beam control through the collaboration of different array antennas to achieve precise coverage and directional transmission of signals.

[0064] like Figure 1 As shown, process 100 may be executed by an electronic device or a processor, and may include the following operations.

[0065] Step 101, in a signal transmission mode, modulate and encode a data packet to be transmitted by a wireless signal transceiver to obtain a radio frequency signal to be transmitted.

[0066] After the wireless signal transceiver receives the digital data packet to be sent, it can use modulation technology (such as QAM, PSK, etc.) to encode the data into a radio frequency signal.

[0067] Step 102: Send the radio frequency signal to be sent to the power amplifier.

[0068] Radio frequency signals generally refer to electromagnetic wave signals with frequencies between 3kHz and 300GHz, which can be used for wireless communication.

[0069] Step 103: amplify the radio frequency signal to be transmitted by the power amplifier and then transmit the amplified signal to the multi-stage array antenna.

[0070] The modulated RF signal can be transmitted to a power amplifier for power boosting. The input end of the power amplifier is connected to a wireless signal transceiver, and the output end is connected to a multi-stage array antenna.

[0071] Step 104: Analyze the amplified radio frequency signal through the multi-stage array antenna to determine the transmission direction of the radio frequency signal.

[0072] After receiving the amplified RF signal, the multi-stage array antenna can analyze the best transmission direction according to the environment and communication requirements. In some embodiments, the signal analysis can be performed based on the phase and amplitude distribution between antenna units.

[0073] The emission direction can be a single direction or multiple different directions.

[0074] Step 105: Based on the transmission direction, determine the primary array antenna and the secondary array antenna for performing beam shaping and direction on the radio frequency signal.

[0075] Based on the analysis results, the system can determine the appropriate combination of primary and secondary array antennas to achieve optimal signal coverage and direction control.

[0076] The primary array antenna is used to adjust the phase and amplitude of each antenna element to form a beam of a specific shape. The beam shape determines the distribution of energy transmitted by the antenna in different directions.

[0077] The secondary array antenna is used to adjust the phase and amplitude of each unit to determine the actual transmission direction of the beam without changing the beam shape.

[0078] In some embodiments, the determining, based on the transmission direction, a primary array antenna and a secondary array antenna for beam shaping and directing the radio frequency signal includes:

[0079] S10, based on the transmission direction, determine the main axis of the multi-stage array antenna.

[0080] The main axis of a multi-stage array antenna refers to the central axis of the array antenna, which determines the initial transmission direction of the antenna. The main axis can be set according to the transmission direction and is the basis of beam pointing.

[0081] The system can determine the main axis of the multi-stage array antenna according to the transmission direction of the signal, ensuring that the transmission direction of the antenna system is consistent with the communication target.

[0082] S11, determining the distance between each antenna unit in the multi-stage array antenna and the main axis.

[0083] The distance between the antenna unit and the main axis refers to the spatial position distance of each antenna unit (antenna element) in the multi-stage array antenna relative to the main axis. This distance affects the beamforming effect of the signal and the accuracy of directional control.

[0084] The system can calculate the distance from each antenna unit in the multi-stage array antenna to the main axis one by one.

[0085] S12, clustering the multiple antenna units based on the distance to obtain the primary array antenna.

[0086] Clustering involves dividing antenna elements into different groups based on their distance from the main axis. The goal is to optimize the antenna configuration so that each group of elements has similar performance characteristics.

[0087] By clustering the distances between the antenna units and the main axis, multiple antenna units are divided into different groups. The clustering algorithm can use algorithms such as K-means to group antenna units with similar distances into the same group to form a primary array antenna.

[0088] Clustering processing can optimize the coverage and directivity of the signal, making the configuration of the first-level array antenna more efficient.

[0089] S13, taking each antenna unit in the primary array antenna as the center, recalling a plurality of candidate secondary antennas based on the distances between the antenna units.

[0090] Recalling candidate secondary antennas refers to screening out secondary antenna units that may be used for beamforming from a multi-stage array antenna based on distance and performance.

[0091] On the premise that each antenna unit of the primary array antenna has been determined, a plurality of candidate antenna units that can be used as the secondary array antenna can be selected based on the distances between the antenna units and with the primary unit as the center.

[0092] S14, performing amplitude and phase evaluation based on the multiple candidate secondary antennas, and determining the secondary array antenna from the multiple candidate secondary antennas based on the evaluation result.

[0093] Amplitude and phase evaluation refers to analyzing the signal amplitude and phase of the candidate secondary antenna unit to evaluate its contribution to beamforming. The amplitude determines the signal strength, while the phase affects the superposition and synthesis effect of the signal.

[0094] The system can conduct a detailed evaluation of the amplitude and phase of the recalled multiple candidate secondary antennas. The evaluation criteria may include signal coverage, directivity, gain effect, etc. Based on the evaluation results, the most suitable unit as the secondary antenna can be selected to achieve the best beamforming effect.

[0095] In some embodiments, the performing amplitude and phase evaluation based on the multiple candidate secondary antennas includes:

[0096] S141, determining the position coordinates of each of the candidate secondary antennas in the multi-stage array antenna.

[0097] The position coordinates refer to the physical position of the antenna unit in the multi-stage array antenna, which can be expressed in a two-dimensional or three-dimensional coordinate system (such as (x, y, z)). The position coordinates reflect the relative position between antenna units and the directionality of signal propagation.

[0098] In some embodiments, the position coordinates may be obtained through the geometric layout of the antenna units. For example, a coordinate system may be constructed in advance based on the arrangement of the multi-stage array antennas, and the position coordinates of each antenna unit may be obtained.

[0099] S142: construct a candidate secondary antenna coordinate distribution map based on the position coordinates.

[0100] The coordinate distribution diagram is a two-dimensional or three-dimensional distribution diagram constructed by the position coordinates of the candidate antenna units, which reflects the arrangement of the candidate antenna units in the entire array. The coordinate distribution diagram provides the basis for subsequent signal processing and pattern construction.

[0101] Based on the position coordinates of the candidate secondary antennas, the system can construct a coordinate distribution diagram, which can intuitively reflect the relative positions of the candidate secondary antennas and the position distribution of the candidate secondary antennas in the multi-stage array antenna.

[0102] S143, determining a directional pattern based on the secondary antenna coordinate distribution diagram and the amplitude and phase of each antenna unit in the candidate secondary antenna.

[0103] The radiation pattern is a graph that reflects the radiation intensity based on the amplitude and phase of the antenna unit. It is used to show the radiation intensity of the signal in different directions.

[0104] In some embodiments, a directivity pattern may be generated based on the coordinate distribution diagram of the candidate secondary antennas and in combination with the amplitude and phase of each antenna element. The amplitude determines the strength of the signal, while the phase determines the coherence of the signal and the effect of beamforming. Through the combination of these parameters, a directivity pattern may be calculated to show the distribution of the radiation intensity of the signal in different transmission directions.

[0105] S144: Based on the directional pattern, determine the radiation intensities of different candidate secondary antenna combinations in the transmission direction.

[0106] Based on the directional diagram, different candidate secondary antennas are combined, and their corresponding amplitudes and phases are combined and calculated to obtain the radiation intensity of different candidate secondary antenna combinations in the transmission direction.

[0107] After sorting the radiation intensities of different combinations according to their sizes, the most suitable candidate secondary antenna combination can be obtained.

[0108] In some embodiments, the determining of the radiation intensities of different candidate secondary antenna combinations in the transmission direction based on the directional pattern may also be performed in the following manner.

[0109] The directional pattern is input into a preset radiation intensity evaluation model to obtain the radiation intensity of the different candidate secondary antenna combinations in the transmission direction. The output result of the radiation intensity evaluation model is a radiation matrix composed of multiple vectors, each vector representing a different candidate secondary antenna combination and its corresponding radiation intensity.

[0110] The radiation intensity evaluation model is a mathematical model used to calculate the radiation intensity of an antenna in different directions. Based on the physical parameters of the antenna (such as amplitude, phase, coordinates) and the signal processing algorithm, the model can output a radiation intensity matrix for evaluating the performance of different antenna combinations.

[0111] The radiation intensity matrix consists of multiple vectors, each of which represents the radiation intensity of different candidate secondary antenna combinations in a specific transmission direction. The matrix form allows the system to quickly compare the pros and cons of different combinations and determine the best antenna configuration solution.

[0112] Step 106: Perform beam synthesis on the radio frequency signals of the primary array antenna and the secondary array antenna to obtain a beam synthesis signal.

[0113] Beamforming is the process of superimposing the signals of multiple antenna units to form a directional beam by controlling the phase and amplitude of the antenna units.

[0114] In some embodiments, a beamforming function for beamforming the radio frequency signal using the primary array antenna and the secondary array antenna is shown in the following formula (1).

[0115] (1)

[0116] Wherein, F represents the result of beam synthesis, N1 is the number of antenna units of the primary array antenna, Wn is the amplitude and phase weight of each antenna unit in the primary array antenna, j is the imaginary unit, k is the wave number, d is the distance between antenna units, θ is the angle of the observation direction relative to the main axis of the array; N2 is the number of antenna units of the secondary array antenna, Vm is the amplitude and weight of each antenna unit in the secondary array antenna, d2 is the distance between the secondary array antenna units, and φ is the angle of the transmission direction.

[0117] It can be understood that the multi-stage array antenna in the embodiment of the present invention can be a linear array or a nonlinear array, and both the linear array and the nonlinear array can adopt the above formula (1).

[0118] In some embodiments, when the multi-stage array antenna is a nonlinear array, in order to improve signal stability and transmission performance, the beamforming function for beamsynthesizing the RF signal using the primary array antenna and the secondary array antenna can also be as shown in the following formula (2).

[0119] (2)

[0120] Among them, xn and yn are the coordinate positions of the nth antenna unit in the primary array antenna in the two-dimensional plane; xm and ym are the coordinate positions of the mth antenna unit in the secondary array antenna in the two-dimensional plane.

[0121] Step 107: Send the beam synthesis signal according to the transmission direction through the multi-stage array antenna.

[0122] The beamformed signal will be amplified and sent out along the transmission direction through a multi-stage array antenna to achieve communication.

[0123] In some embodiments, based on the same inventive concept, a wireless communication method based on a radio frequency transceiver circuit provided by the present invention also includes processing of signal reception in wireless communication.

[0124] In a signal receiving mode, receiving wireless signals through the multi-stage array antenna;

[0125] Analyze the wireless signal through the multi-stage array antenna to determine a primary array antenna and a secondary array antenna for processing the wireless signal;

[0126] Processing the wireless signal through the primary array antenna and the secondary array antenna to obtain a received signal, and sending the received signal to the power amplifier;

[0127] Performing low-noise amplification on the received signal by the power amplifier;

[0128] The amplified received signal is demodulated and decoded through the baseband to obtain the original data packet.

[0129] In the above method, the phase alignment and amplitude weighting of the received signal can be performed by the primary array antenna; and the directionality enhancement of the received signal can be performed by the secondary array antenna.

[0130] The specific method of processing the wireless signal may be as shown in the following formula (3).

[0131] (3)

[0132] Wherein, S represents the weighted sum of the signals of all antenna units of the primary array antenna and the secondary array antenna, Fm is the weighting coefficient of the primary array antenna, Sn is the weighting coefficient of the secondary array antenna, An is the signal amplitude received by the nth antenna unit of the primary array antenna, is the original data and phase change of the received signal, and P represents the phase change of the received signal in the multi-level array antenna.

[0133] For detailed descriptions of each step in the signal receiving mode, please refer to the relevant descriptions in the signal sending mode, which will not be repeated here.

[0134] The working principle of the present invention is to perform beamforming and signal processing based on a multi-stage array antenna of a radio frequency transceiver circuit to improve the transmission and reception efficiency of wireless communication. Through the configuration of the multi-stage array antenna, combined with the amplitude and phase information of the antenna unit, optimized beam synthesis is achieved in different directions to achieve efficient signal transmission and reception.

[0135] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
