[0022] Step 101: Obtain data to be sent.

[0023] Step 102: Arbitrarily select a sub-frame from the information frame of the data to be sent as a power servo frame.

[0024] The processor may obtain the data to be sent. Among them, the data to be sent may be the data that the transmitter is to send. After obtaining the data to be sent, the processor may arbitrarily select a sub-frame from the information frame of the data to be sent as a power servo frame.

[0025] In the embodiment of this application, the processing method further includes: after arbitrarily selecting a sub-frame from the information frame of the data to be sent as a power servo frame, perform symbol mapping on the power servo frame.

[0026] After arbitrarily selecting a sub-frame from the information frame of the data to be sent as the power servo frame, the processor can perform symbol mapping on the power servo frame. In an optional embodiment, the processor can use 8-bit significant bits, ranging from 1 to , with the highest bit being the sign bit and the starting amplitude being ±64*sqrt(2) / 2 to perform symbol mapping on the power servo frame.

[0027] Step 103: Perform baseband processing and power adjustment on the power servo frame to obtain the processed power servo frame.

[0028] After obtaining the power servo frame, the processor can perform baseband processing and power adjustment on the power servo frame to obtain the processed power servo frame. Among them, the baseband processing can include shaping filter processing, upsampling filter processing, and IQ modulation, etc. IQ modulation is a method of dividing the signal into two paths for carrier modulation, where the two carriers are orthogonal to each other. I represents the in-phase component, and Q represents the quadrature component.

[0029] In the embodiment of the present application, performing baseband processing and power adjustment on the power servo frame to obtain the processed power servo frame includes: adjusting the power of the power servo frame within the first preset range based on the first-level power control parameter to obtain the adjusted first power servo frame; performing baseband processing on the first power servo frame to obtain the second power servo frame, where the baseband processing includes filtering, sampling, and quadrature modulation; adjusting the power of the second power servo frame within the second preset range based on the second-level power control parameter to obtain the processed power servo frame, where the lower limit value of the second preset range is greater than the upper limit value of the first preset range.

[0030] The processor can perform baseband processing and power adjustment on the power servo frame to obtain the processed power servo frame. Specifically, the processor can adjust the power of the power servo frame within the first preset range based on the first-level power control parameter to obtain the adjusted first power servo frame. In a specific embodiment, the first-level power control parameter P1 can be 127. After obtaining the first power servo frame, the processor can perform baseband processing on the first power servo frame to obtain the second power servo frame, where the baseband processing includes filtering, sampling, and quadrature modulation, specifically, it can be shaping filter, upsampling, and IQ modulation. After obtaining the second power servo frame, the processor can adjust the power of the second power servo frame within the second preset range based on the second-level power control parameter to obtain the processed power servo frame. In a specific embodiment, the second-level power control parameter P2 can be 2. Among them, the lower limit value of the second preset range is greater than the upper limit value of the first preset range. For example, the first preset range can be 0 to 6 dB, and the second preset range can be 6 dB to 60 dB.

[0031] In an embodiment of the present application, adjusting the power of a power servo frame based on a first-level power control parameter within a first preset range to obtain an adjusted first power servo frame includes: obtaining the fractional part and the integer part of the power of the power servo frame; adjusting the fractional part based on the first-level power control parameter within the first preset range to obtain the first power servo frame.

[0032] The processor may adjust the power of the power servo frame based on the first-level power control parameter within the first preset range to obtain an adjusted first power servo frame. Specifically, the processor may obtain the fractional part and the integer part of the power of the power servo frame. After obtaining the fractional part of the power servo frame, the processor may adjust the fractional part based on the first-level power control parameter within the first preset range to obtain the first power servo frame. For example, if the first preset range is from 0 to 6 dB, the processor may perform power adjustment of the fractional part within 6 dB.

[0033] In an embodiment of the present application, adjusting the power of a second power servo frame based on a second-level power control parameter within a second preset range to obtain a processed power servo frame includes: adjusting the integer part based on the second-level power control parameter within the second preset range to obtain the processed power servo frame.

[0034] The processor may adjust the power of the second power servo frame based on the second-level power control parameter within the second preset range to obtain a processed power servo frame. Specifically, the processor may obtain the fractional part and the integer part of the power of the power servo frame. After obtaining the integer part of the power servo frame, the processor may adjust the integer part based on the second-level power control parameter within the second preset range to obtain the processed power servo frame. For example, if the second preset range is from 6 dB to 60 dB, the processor may perform integer part adjustment outside 6 dB.

[0035] In an embodiment of the present application, the processing method further includes: after determining the current power of the processed power servo frame, updating the first-level power control parameter and the second-level power control parameter based on a power error.

[0036] After determining the current power of the processed power servo frame, the processor may update the first-level power control parameter and the second-level power control parameter based on the power error.

[0037] In an embodiment of the present application, the processing method further includes: after determining the current power of the processed power servo frame, obtaining the in-phase component and the quadrature component of the processed power servo frame; determining the sum of the square of the in-phase component and the square of the quadrature component as the current power.

[0038] After determining the current power of the processed power servo frame, the processor can obtain the in-phase component and the quadrature component of the processed power servo frame. After obtaining the in-phase component and the quadrature component, the processor can determine the sum of the square of the in-phase component and the square of the quadrature component as the current power, that is, the current power , where I is the in-phase component and Q is the quadrature component.

[0039] Step 104: Determine the current power of the processed power servo frame.

[0040] Step 105: When the power error between the current power and the preset target power is greater than the preset value, return to the step of arbitrarily selecting a sub-frame from the information frame as the power servo frame again until the power error is less than the preset value.

[0041] Step 106: When the power error is less than the preset value, determine that the convergence of the processed power servo frame is completed.

[0042] Step 107: Perform baseband processing on all the power servo frames for which the convergence is completed to obtain the target digital waveform of the data to be transmitted.

[0043] After obtaining the processed power servo frame, the processor can determine the current power of the processed power servo frame. After obtaining the current power of the processed power servo frame, the processor can determine the power error between the current power of the processed power servo frame and the preset target power. Among them, the preset target power can be determined based on the actual situation. For example, the preset target power is 55.3 dB. After obtaining the power error between the current power and the preset target power, the processor can determine whether the power error between the current power and the preset target power is greater than the preset value. The preset value can be determined based on the actual situation. For example, it can be 0.15 dB. When the power error between the current power and the preset target power is greater than the preset value, the processor can return to the step of arbitrarily selecting a sub-frame from the information frame as the power servo frame again until the power error is less than the preset value. When the power error is less than the preset value, the processor can determine that the convergence of the processed power servo frame is completed. After determining that the convergence of the processed power servo frame is completed, the processor can perform baseband processing on all the power servo frames for which the convergence is completed to obtain the target digital waveform of the data to be transmitted.

[0044] In an embodiment of the present application, the processing method further includes: after determining the current power of the processed power servo frame, obtaining the usage duration of the current iteration; in the case where the usage duration is greater than a preset duration, returning again to the step of arbitrarily selecting a sub-frame from the information frame as the power servo frame until the usage duration is less than the preset duration; in the case where the usage duration is less than the preset duration, determining that the iteration is completed; performing baseband processing on the power servo frame after the iteration is completed to obtain the target digital waveform of the data to be transmitted.

[0045] After determining the current power of the processed power servo frame, the processor can obtain the usage duration of the current iteration. After obtaining the usage duration of the current iteration, the processor can determine whether the usage duration of the current iteration is greater than a preset duration, where the preset duration can be determined according to the actual situation, such as 10 frames. In the case where the usage duration is greater than the preset duration, the processor can return again to the step of arbitrarily selecting a sub-frame from the information frame as the power servo frame until the usage duration is less than the preset duration. In the case where the usage duration is less than the preset duration, the processor can determine that the iteration is completed. After the iteration is completed, the processor can perform baseband processing on the power servo frame after the iteration is completed to obtain the target digital waveform of the data to be transmitted.

[0046] In an embodiment of the present application, as Figure 2 shown, a data processing method is provided, and the method includes the following steps: S1: Taking a continuous segment of bits in the information to be transmitted as power servo feature data.

[0047] The processor can take a continuous segment of bits in the information to be transmitted as power servo feature data. After obtaining the power servo feature data, the processor can perform parameter training on the power servo feature data and set FLAG to 1.

[0048] S2: Reading the power servo feature data in a loop for training.

[0049] S3: Digital transmitter baseband processing.

[0050] The processor can read the power servo feature data in a loop for training and perform baseband processing on the power servo feature data through the digital transmitter.

[0051] S301: Symbol mapping.

[0052] S302: Small dynamic range power control (parameter P1).

[0053] S303: Baseband processing.

[0054] S304: Large dynamic range power control (parameter P2).

[0055] S305: Calculate power closed-loop control parameters and update P1 and P2.

[0056] S4: Read all sub-frame information and send it to baseband processing.

[0057] The processor can perform symbol mapping on the servo characteristic data. Specifically, 8-bit or 16-bit significant bits can be used, with a range from 1 to , where the highest bit is the sign bit, and the starting amplitude is ±64*sqrt(2) / 2 for symbol mapping of the power servo frame. The processor can set the initial first-stage power control parameter P1 to 127 for power control within 6 dB. After completing the power control in the small dynamic range, the processor can perform power control in the large dynamic range after subjecting the power servo frame after control to baseband processing such as shaping filtering, upsampling, and IQ modulation. Specifically, the processor can set the initial second-stage power control parameter P2 to 2 for power control outside 6 dB. The processor can calculate the power closed-loop control parameters to update P1 and P2. Specifically, the processor can determine the current power based on the in-phase component and quadrature component of the power servo characteristic data. After obtaining the current power, the processor can determine the power error between the current power and the preset target power. Among them, the preset target power can be set to 55.3 dB.

[0058] The processor can determine whether it is still in the parameter training stage. When still in the parameter training stage, the processor can determine whether the power error between the current power of the power servo characteristic data and the preset target power is greater than the threshold THD, where the threshold THD can be set to 0.15 dB. The processor can determine whether the training times out. When the power error is greater than the threshold THD or the training times out, the processor can return to the step of circularly reading the power servo characteristic data for training until the power error is less than the threshold THD and the training does not time out. The processor can set the parameter training FLAG to 0, read all sub-frame information and send it to baseband processing, and return to the symbol mapping step until the target power digital waveform is output, as Figure 3 shown in the target power digital waveform, where X equals 7977 indicates that the target power digital waveform is the data to be transmitted at the 7997th sampling point of the transmitter, Y equals 1.001 indicates the ratio between the current power of the target digital waveform and the preset target power, and the power of the target power digital waveform can converge to 55.208 dB with an error of 0.092 dB.

[0059] Through the above technical solution, it is possible to achieve the convergence of data before data transmission, accurately perform power control, and reduce power fluctuations.
