[0039] Embodiment one

[0040] Figure 1 A flowchart of a transmit power adjustment method provided by the embodiment one of the present application, the method can be applied to the case of transmitting Beidou short message by Beidou communication terminal, the method can be executed by a transmit power adjustment device, wherein the device can be realized by software and / or hardware, and is generally integrated on an electronic device.

[0041] As Figure 1 shown, the transmit power adjustment method provided by the embodiment one of the present application comprises the following steps:

[0042] S110, within the first preset time after starting, a satellite beam carrier-to-noise ratio storage table is constructed.

[0043] The first preset time can be understood as the time after the device is started, which can be set in advance, for example, the satellite beam carrier-to-noise ratio storage table can be constructed immediately after the device is started, or the satellite beam carrier-to-noise ratio storage table can be constructed within 1 minute after the device is started.

[0044] It should be understood that under vacuum conditions, the Beidou signal power received on the ground, i.e., the receiving power of the Beidou satellite beam to the ground, is represented by the following formula:

[0045] P r = P t + G t + Gr +20log 10 C-20log 10 (4πdf)

[0046] wherein, P t represents satellite transmitting power, unit dB; G t represents satellite transmitting antenna gain, unit dB; G r represents Beidou communication terminal receiving antenna gain, unit dB; C represents the transmission rate of electromagnetic wave in vacuum, taking 3x e 8 m / s; d represents the distance from satellite to the ground, unit m, f represents electromagnetic wave frequency, unit Hz. P t and G t sum represents the equivalent isotropic radiated power of satellite transmitting; 20log 10 C-20log 10 (4πdf) represents the attenuation value of electromagnetic wave in free space.

[0047] On the basis of the above formula, the signal attenuation term caused by wireless channel attenuation parameter can be added, and by selecting the signal receiving power under different weather and different environment, different signal receiving power reflects different channel attenuation difference. The calculation formula of Beidou signal receiving power after adding wireless channel attenuation parameter is as follows:

[0048] P r =EIRPt+Gr+ILair-ILenvi

[0049] wherein, EIRPt represents the equivalent isotropic radiated power of satellite transmitting, unit dB; G r represents Beidou communication terminal receiving antenna gain, unit dB; ILair represents the attenuation value of electromagnetic wave in free space, unit dB; ILenvi represents wireless channel attenuation parameter, unit dB.

[0050] In the process of receiving Beidou signal, the received signal power P r can be estimated by the beam carrier-to-noise ratio C / N0 of Beidou signal, and the calculation formula is as follows:

[0051] P r =-174+C / N0

[0052] Wherein, C / N0 can be obtained by signal analysis of receiving terminal, and can be obtained in real time.

[0053] It can be understood that the power value of different satellite beams reaching the ground is different, but the value of C / N0 has the characteristics of stationary random process under normal environmental conditions, so a plurality of sample values C / N0 i,j, j represents a satellite beam number, j = 1, 2, 3, …, M, and i represents a sampling sample value sequence number, i = 1, 2, 3, …, N.

[0054] At present, the total number of beam numbers of the Beidou No. 3 RDSS is 21, but the number of beams received in different regions is different, and usually more than 10 beams can be received, and the number M of satellite beams can be determined according to actual conditions; the number N of samples can be selected according to actual conditions, and usually the number of samples is selected to be more than 100.

[0055] According to the plurality of satellite beam carrier-to-noise ratio sample values C / N0 i,j A satellite beam carrier-to-noise ratio storage table can be constructed, as shown in Table 1, which is a satellite beam carrier-to-noise ratio storage table provided by Embodiment One of the present application.

[0056]

[0057] Table 1

[0058] In the satellite beam carrier-to-noise ratio storage table, the carrier-to-noise ratio values corresponding to different Beidou satellite beams are included, and one Beidou satellite beam corresponds to a plurality of carrier-to-noise ratio values.

[0059] S120, determining the first average received power of the selected at least one candidate Beidou satellite beam reaching the ground based on the satellite beam carrier-to-noise ratio storage table, and storing the first average received power of the at least one candidate Beidou satellite beam reaching the ground in a lookup table.

[0060] In the first average received power, the first is a designation to distinguish the received power, and does not have actual meaning. The candidate Beidou satellite beam can be used as a candidate beam for Beidou signal transmission. The lookup table can be a pre-set table, and can record a plurality of average received powers.

[0061] In this embodiment, according to the satellite beam carrier-to-noise ratio storage table, at least one Beidou satellite beam can be selected from the M Beidou satellite beams in the table as a candidate Beidou satellite beam, and after removing the error carrier-to-noise ratio values in the Beidou satellite beams, the average received power of each candidate Beidou satellite beam reaching the ground can be calculated according to the plurality of satellite beam carrier-to-noise ratios C / N0 corresponding to each candidate Beidou satellite beam.

[0062] The way of selecting the Beidou satellite candidate beam can be various, which is not specifically limited here. It should be noted that the average received power of each candidate Beidou satellite beam reaching the ground can be directly calculated according to the plurality of satellite beam carrier-to-noise ratios corresponding to each candidate Beidou satellite beam, and preferably, the average received power of each candidate Beidou satellite beam reaching the ground can be calculated after removing the error carrier-to-noise ratio values in each candidate Beidou satellite beam.

[0063] Exemplarily, beam 1, beam 3 and beam 7 are selected from the M Beidou satellite beams in the Beidou satellite beam carrier-to-noise ratio storage table as Beidou satellite candidate beams, 2 error carrier-to-noise ratio values are removed from the N carrier-to-noise ratio values in beam 1, and the carrier-to-noise ratio values in beam 1 are N-2, the average receiving power of beam 1 reaching the ground can be calculated according to the N-2 carrier-to-noise ratio values; similarly, 5 error carrier-to-noise ratio values are removed from the N carrier-to-noise ratio values in beam 2, and the carrier-to-noise ratio values in beam 2 are N-5, the average receiving power of beam 2 reaching the ground can be calculated according to the N-5 carrier-to-noise ratio values; the average receiving power of beam 3 reaching the ground can be calculated according to the above process, which will not be described here.

[0064] S130, determine the basic transmission power of the Beidou signal, and store the basic transmission power in the lookup table.

[0065] The basic transmission power can be used as the transmission power of the Beidou signal, and the basic transmission power can be determined in various ways, which will not be specifically limited here, and needs to satisfy that the success rate of multiple Beidou signal self-transmission and self-reception according to the basic transmission power is higher than a preset value.

[0066] S140, select a target Beidou satellite beam from the at least one candidate Beidou satellite beam, determine the second average receiving power of the target Beidou satellite beam reaching the ground within a second preset time before signal transmission, and store the second average receiving power in the lookup table.

[0067] The second preset time is later than the first preset time, and exemplarily, the first preset time is from 9:00 to 9:05, and the second preset time is from 9:05 to 9:10.

[0068] In this embodiment, the first selected beam, the second selected beam and the third selected beam can be selected as the target Beidou satellite beam according to the average carrier-to-noise ratio of the candidate Beidou satellite beam. First, the first selected beam is used as the target Beidou satellite beam, at this time, N carrier-to-noise ratio values of the first selected beam within the second preset time are collected, if there are error values in the N carrier-to-noise ratio values of the first selected beam within the second preset time, the second selected beam can be used as the target Beidou satellite beam, N carrier-to-noise ratio values of the second selected beam within the second preset time are collected, if there are error values in the N carrier-to-noise ratio values of the second selected beam within the second preset time, the third selected beam can be used as the target Beidou satellite beam, N carrier-to-noise ratio values of the third selected beam within the second preset time are collected, and the average receiving power of the target Beidou satellite beam reaching the ground within the second preset time, i.e. the second average receiving power, is calculated.

[0069] The calculation method of the second average power can include the following two methods:

[0070] In the first mode, the average value of N C / N0 values included in the target Beidou satellite beam is calculated, and the second average received power of the target Beidou satellite beam reaching the ground is calculated according to the formula P = -174 + C / N0. r

[0071] In the second mode, i deviated C / N0 values are determined from N C / N0 values included in the target Beidou satellite beam, the average value of the remaining N-i C / N0 values is calculated, and the second average received power of the target Beidou satellite beam reaching the ground is calculated according to the formula P = -174 + C / N0. r

[0072] The first mode is preferred in the above two modes.

[0073] S150, adjusting the basic transmission power in the lookup table based on the first average received power of the target Beidou satellite beam reaching the ground and the second average received power of the target Beidou satellite beam reaching the ground included in the lookup table.

[0074] In the embodiment, the basic transmission power and the first average received power of the target satellite beam reaching the ground can be obtained from the lookup table. Before the Beidou signal is transmitted, the second average received power of the target Beidou satellite beam reaching the ground is read, the received power change is calculated according to the first average received power and the second average received power, and the basic transmission power is adjusted based on the received power change when the received power change is greater than a preset value.

[0075] ​​The embodiment one of the present application provides a transmitting power adjustment method, first, a satellite beam carrier-to-noise ratio storage table is constructed within a first preset time after starting, the satellite beam carrier-to-noise ratio storage table includes carrier-to-noise ratio values corresponding to different Beidou satellite beams, and one Beidou satellite beam corresponds to multiple carrier-to-noise ratio values; second, the first average receiving power of the selected at least one candidate Beidou satellite beam reaching the ground is determined based on the satellite beam carrier-to-noise ratio storage table, and the first average receiving power of the at least one candidate Beidou satellite beam reaching the ground is stored in a lookup table; then the basic transmitting power of the Beidou signal is determined, and the basic transmitting power is stored in the lookup table; then a target Beidou satellite beam is selected from the at least one candidate Beidou satellite beam, the second average receiving power of the target Beidou satellite beam reaching the ground within a second preset time before signal transmission is determined, and the second average receiving power is stored in the lookup table; finally, the basic transmitting power in the lookup table is adjusted based on the first average receiving power of the target Beidou satellite beam reaching the ground and the second average receiving power of the target Beidou satellite beam reaching the ground included in the lookup table. By using the above method, the size of the transmitting power can be adaptively adjusted to adapt to different transmitting power requirements, and the problem of power waste caused by uniformly using the maximum transmitting power for signal transmission is solved.

[0076] On the basis of the above-mentioned embodiments, variant embodiments of the above-mentioned embodiments are proposed, and it should be noted that, in order to make the description brief, only the differences from the above-mentioned embodiments are described in the variant embodiments.

[0077] In one embodiment, selecting the target Beidou satellite beam from the at least one candidate Beidou satellite beam comprises:

[0078] The first carrier-to-noise ratio mean corresponding to the at least one candidate Beidou satellite beam is sequentially determined from the at least one candidate Beidou satellite beam in descending order, to determine a first selected beam, a second selected beam and a third selected beam; one of the first selected beam, the second selected beam and the third selected beam is selected as the target Beidou satellite beam, and the first selected beam is preferentially selected as the target Beidou satellite beam.

[0079] Embodiment two

[0080] Figure 2a A flowchart of a transmitting power adjustment method provided for the embodiment two of the present application, the embodiment two is optimized on the basis of the above-mentioned embodiments. In the embodiment, the first average receiving power of the selected at least one candidate Beidou satellite beam reaching the ground is determined based on the satellite beam carrier-to-noise ratio storage table, which is further specified. The details of the embodiment are referred to the embodiment one.

[0081] As Figure 2aAs shown, the method for adjusting transmitting power provided by the second embodiment of the present application comprises the following steps:

[0082] S210, constructing a satellite beam carrier-to-noise ratio storage table within a first preset time after starting up.

[0083] The satellite beam carrier-to-noise ratio storage table comprises carrier-to-noise ratio values corresponding to different Beidou satellite beams, and one Beidou satellite beam corresponds to multiple carrier-to-noise ratio values.

[0084] S220, calculating a first carrier-to-noise ratio mean value and a first carrier-to-noise ratio variance corresponding to each Beidou satellite beam in the satellite beam carrier-to-noise ratio storage table.

[0085] The calculation method of the carrier-to-noise ratio mean value and the carrier-to-noise ratio variance corresponding to each Beidou satellite beam is the same, and the calculation method of one Beidou satellite beam is described as an example. According to N carrier-to-noise ratio values of one Beidou satellite beam, the mean value and the variance of the N carrier-to-noise ratio values can be calculated.

[0086] The at least one candidate Beidou satellite beam can be determined from the multiple Beidou satellite beams according to the size of the carrier-to-noise ratio mean value corresponding to each Beidou satellite beam.

[0087] In one embodiment, the method for determining the at least one candidate Beidou satellite beam can be as follows: the multiple Beidou satellite beams are sorted in descending order of the first carrier-to-noise ratio mean value; and the Beidou satellite beams within a preset number range in the sorted order are determined as the candidate Beidou satellite beams.

[0088] For example, the multiple Beidou satellite beams are sorted in descending order of the carrier-to-noise ratio mean value corresponding to each Beidou satellite beam, and the Beidou satellite beams within the top 3 positions in the sorted order are determined as the candidate Beidou satellite beams.

[0089] S240, according to the first carrier-to-noise ratio variance corresponding to the at least one candidate Beidou satellite beam, re-calculating a second carrier-to-noise ratio mean value corresponding to the at least one candidate Beidou satellite beam after excluding the values deviating from the corresponding first carrier-to-noise ratio mean value by more than a preset value from the multiple first carrier-to-noise ratio values corresponding to the at least one candidate Beidou satellite beam.

[0090] For example, taking a candidate Beidou satellite beam as an example, the carrier-to-noise ratio mean value corresponding to the candidate Beidou satellite beam is 5 dB, and the carrier-to-noise ratio mean value is removed from the carrier-to-noise ratio values deviating from the candidate Beidou satellite beam according to the carrier-to-noise ratio variance of the candidate Beidou satellite beam. The carrier-to-noise ratio values deviating from the carrier-to-noise ratio mean value 5 dB by more than 2 dB are removed, and the carrier-to-noise ratio mean value is recalculated using the remaining carrier-to-noise ratio values after removing the carrier-to-noise ratio values deviating from the candidate Beidou satellite beam.

[0091] S250, calculating the first average received power of the at least one candidate Beidou satellite beam reaching the ground according to the second carrier-to-noise ratio mean value, and storing the first average received power of the at least one candidate Beidou satellite beam reaching the ground in the lookup table.

[0092] For example, taking a candidate Beidou satellite beam as an example, the second carrier-to-noise ratio mean value C / N0 of the candidate Beidou satellite beam is calculated through step S240, and the first average received power of the candidate Beidou satellite beam reaching the ground can be calculated according to the formula P r = -174 + C / N0.

[0093] S260, determining the basic transmission power of the Beidou signal, and storing the basic transmission power in the lookup table.

[0094] S270, selecting a target Beidou satellite beam from the at least one candidate Beidou satellite beam, determining the second average received power of the target Beidou satellite beam reaching the ground within a second preset time before signal transmission, and storing the second average received power in the lookup table.

[0095] Wherein, the second preset time is later than the first preset time.

[0096] S280, adjusting the basic transmission power in the lookup table based on the first average received power of the target Beidou satellite beam reaching the ground and the second average received power of the target Beidou satellite beam reaching the ground included in the lookup table.

[0097] The second embodiment of the application provides a transmission power adjustment method, which specifically implements the process of selecting candidate Beidou satellite beams and the process of calculating the first average received power. The candidate Beidou satellite beams selected by the method are more accurate, and the first average received power can be accurately calculated through the satellite beam carrier-to-noise ratio.

[0098] The embodiment of the application provides a specific implementation method on the basis of the technical solutions of the above-mentioned embodiments.

[0099] As a specific implementation method of the embodiment, Figure 2bThe flowchart for calculating the carrier-to-noise ratio and selecting beams, as provided in the example embodiment of the present invention, is as follows: Figure 2b As shown, the process includes the following steps: After the device is powered on, it reads the BeiDou signal beams and confirms the maximum number of beams that can be received, M; it sets the number of sampling samples, N, and begins to collect the carrier-to-noise ratio (C / N0); it calculates the mean C / N0 and variance C / N0 of each beam; it selects the top three beams with the highest mean C / N0 as candidate transmit beams; it deducts the C / N0 values ​​of the three candidate beams that deviate from the mean C / N0 by more than 2 dB, and recalculates the mean C / N0 and variance C / N0 of the three candidate beams; it selects the beam with the highest mean C / N0 among the three candidate beams as the first choice for transmit beams, and then sets the second and third choice beams in sequence; it calculates the average received power Pr0 of the selected satellite beam reaching the ground based on the mean C / N0 of the selected satellite beam and stores it in a lookup table.

[0100] Example 3

[0101] Figure 3a This is a flowchart illustrating a transmission power adjustment method according to Embodiment 3 of the present invention. Embodiment 3 is an optimization based on the above embodiments. In this embodiment, the process of determining the basic transmission power of the BeiDou signal is further specified. For details not covered in this embodiment, please refer to Embodiments 1 and 2.

[0102] like Figure 3a As shown, the transmission power adjustment method provided in Embodiment 3 of the present invention includes the following steps:

[0103] S310. Within the first preset time after power-on, construct a satellite beam carrier-to-noise ratio storage table.

[0104] The satellite beam carrier-to-noise ratio storage table includes carrier-to-noise ratio values ​​corresponding to different BeiDou satellite beams, with one BeiDou satellite beam corresponding to multiple carrier-to-noise ratio values.

[0105] S320. Based on the satellite beam carrier-to-noise ratio storage table, determine the first average received power of at least one selected candidate BeiDou satellite beam reaching the ground, and store the first average received power of the at least one candidate BeiDou satellite beam reaching the ground in a lookup table.

[0106] S330. Determine the first transmission power of the BeiDou signal based on the prior value.

[0107] Among them, the prior value can be understood as the BeiDou signal transmission power value obtained from multiple experiments.

[0108] In this embodiment, the transmission power of the BeiDou signal, i.e., the first transmission power, can be designed based on prior values.

[0109] S340, count a communication success rate of the Beidou signal self-emission and self-reception for multiple times according to the first transmission power.

[0110] Wherein, after obtaining the first transmission power, the Beidou signal self-emission and self-reception for multiple times can be performed according to the first transmission power, and a communication success rate is counted.

[0111] S350, if the communication success rate is greater than or equal to a preset success rate, decrease the first transmission power by a preset step value to obtain a second transmission power until the communication success rate corresponding to the second transmission power is less than the preset success rate.

[0112] Wherein, the preset success rate can be set by the user according to the actual situation, and the value of the preset success rate is not limited here. For example, the preset success rate can be 95%. The preset step value can be understood as the value of the first transmission power set by the preset first time each time, for example, the preset step value can be 0.5dB.

[0113] For example, the first transmission power is decreased by 0.5dB to obtain the second transmission power, and the communication success rate of the Beidou signal self-emission and self-reception for not less than 20 times according to the second transmission power is counted. If the communication success rate is still greater than or equal to 95%, the second transmission power is further decreased by 0.5dB, and the communication success rate is counted again.

[0120] For example, the first transmission power is increased by 0.5 dB to obtain a third transmission power, the Beidou signal is self-transmitted and self-received multiple times according to the third transmission power, the communication success rate is counted, if the communication success rate is less than 95%, the third transmission power is increased by 0.5 dB, the corresponding communication success rate is counted, until the counted communication success rate is greater than or equal to 95%, then the third transmission power corresponding to the communication success rate greater than or equal to 95% is decreased by 0.5 dB as a step value to obtain a fourth transmission power, the Beidou signal is self-transmitted and self-received multiple times according to the fourth transmission power, the communication success rate is counted, if the communication success rate is less than 95%, the fourth transmission power is increased by 0.5 dB, the corresponding communication success rate is counted, until the counted communication success rate is greater than or equal to 95%, and the fourth transmission power corresponding to the communication success rate greater than or equal to 95% plus 1 dB is taken as the basic transmission power of the Beidou signal.
