In addition, in order to better illustrate the disclosure, numerous details is given in specific embodiment below.
It will be appreciated by those skilled in the art that without certain details, the disclosure can equally be implemented.In some instances, for
Method well known to those skilled in the art, means, element and circuit are not described in detail, in order to highlight the purport of the disclosure.
Fig. 1 is the flow chart according to a kind of satellite communication method shown in an exemplary embodiment.This method is applied to defend
Star.As shown in Figure 1, this method includes：
Step 100, the corresponding reception range of signal of each wave beam in satellite is set, wherein the corresponding reception of different wave beams
Range of signal is different.
Step 101, according to the corresponding reception range of signal of each wave beam, the reception mode of the uplink signal of each wave beam is set.
Step 102, each wave beam carries out the uplink signal of received each user terminal according to corresponding reception mode
Processing.
As an example of the present embodiment, the corresponding range of signal that receives of satellite beams can include satellite beams correspondence
Symbol and/or frequency point.For example, if satellite includes the first wave beam and the second wave beam, connecing for the first wave beam can be set
Ranging from first code element is received, the range of receiving of the second wave beam is second code element, wherein, first code element is different from second code element.Again
Such as, if satellite includes the first wave beam and the second wave beam, the range of receiving that can set the first wave beam is the first frequency point, the
The range of receiving of two wave beams is the second frequency point, wherein, the first frequency point is different from the second frequency point.
In the present embodiment, the reception mode set in step 101 can include a variety of.
Example one：The reception mode of the uplink signal of each wave beam is set as only receiving to the upper of the reception range of signal of itself
Row signal.
If for example, the reception range of signal of the first wave beam of satellite be first code element, the reception signal model of the second wave beam
It encloses for second code element, then the uplink that the uplink signal of the first wave beam reception mode can be set as to only receiving first code element is believed
Number, the uplink signal of the second wave beam is received into mode and is set as the uplink signal for receiving second code element.
Example two：The reception mode of the uplink signal of each wave beam is set as receiving to the uplink of the reception range of signal of itself
Signal, and receive the uplink signal of the reception range of signal of adjacent beams.
For example, if the reception range of signal of the first wave beam in satellite were the first frequency point, the reception signal of the second wave beam
The uplink signal of first wave beam and the second wave beam can then be received mode by ranging from the second frequency point, be disposed as both receiving the
The uplink signal of one frequency point also receives the uplink signal of the second frequency point.
For example one and example two, step 102 can include：If the first wave beam is received from the first user terminal
The superposed signal of first uplink signal and the second uplink signal from second user terminal, then lose the superposed signal
Packet processing.Wherein, the first uplink signal and the second uplink signal are in the first wave beam corresponding first and receive range of signal, the
Two wave beams are the adjacent beams of the first wave beam, and the reception mode of the uplink signal of the first wave beam receives range of signal to receive first
The uplink signal for receiving range of signal with second.
Since the transmission range of signal of the first uplink signal is identical with the transmission range of signal of the second uplink signal, so the
When one wave beam receives the first uplink signal and the second uplink signal at the same time, what is received is the first uplink signal and the second uplink
The superposed signal of signal.If satellite can not differentiate the superposed signal, consider that satellite can be straight by the superposed signal for timeliness
Connect packet loss.
For example two, step 102 can also include：If the first wave beam is received on first from the first user terminal
The superposed signal of row signal and the second uplink signal from second user terminal, the second wave beam are received from second user terminal
The second uplink signal, then receive the second uplink signal using the second wave beam, subtracted in the superposed signal received from the first wave beam
Second uplink signal obtains the first uplink signal.Wherein, the first uplink signal and the second uplink signal are in the first wave beam pair
First answered receives range of signal, adjacent beams of second wave beam for the first wave beam, the recipient of the uplink signal of the second wave beam
Formula is to receive the first uplink signal for receiving range of signal and the second reception range of signal.
Using example two, the first wave beam and the second wave beam can both receive the uplink signal for receiving range of signal of itself,
The uplink signal of the reception range of signal of adjacent beams can also be received.In this way, receive the first uplink signal in the first wave beam
In the case of the superposed signal of the second uplink signal, if the second wave beam can be successfully received the second uplink signal, defend
The second uplink signal that star can be successfully received according to the second wave beam, at the superposed signal received to the first wave beam
Reason.Specifically, the second uplink signal can be subtracted from superposed signal, reconstruct obtains the first uplink signal, reduces system packet loss.
The disclosure closes on the uplink signal of wave beam using wave beam coordination reception on star, can close on wave beam according to what is received
The superposed signal that arrives of useful signal reconstructed reception, effectively reduce the communication performance loss of wave beam overlapping region, further promoted
Power system capacity.Meanwhile the disclosure is small to overhead, and it is applied widely, additional time and frequency spectrum resource will not occupied
In the case of can significantly lifting system capacity.
For example two, step 102 further includes：If the first wave beam receives the first uplink letter from the first user terminal
Number and the third uplink signal from third user terminal, then confirm successful reception.Wherein, the first uplink signal is in first wave
Beam corresponding first receives range of signal, and third uplink signal is in the corresponding third of third wave beam and receives range of signal, third
Wave beam is the adjacent beams of the first wave beam, the reception mode of the uplink signal of the first wave beam for receive first receive range of signal and
Third receives the uplink signal of range of signal.
Using example two, the first wave beam and the second wave beam can both receive the uplink signal for receiving range of signal of itself,
The uplink signal of the reception range of signal of adjacent beams can also be received.Believe when same wave beam receives two in different receive
During the uplink signal of number range, the two uplink signals can be accurately identified, confirms and is properly received, reduce packet loss.
Fig. 2 is the flow chart according to a kind of satellite communication method shown in an exemplary embodiment.This method is applied to use
Family terminal, for example, communication terminal, computer equipment, radio navigation device etc. can with the user terminal of satellite communication,
It does not limit herein.As shown in Fig. 2, this method includes：
Step 200, user terminal obtains the position of itself.
Step 201, the orbital position of the satellite is determined according to the ephemeris of satellite.
Step 202, it is laid out according to the position of itself, the orbital position of the satellite and wave beam, determines the user terminal
The corresponding reception range of signal of satellite beams accessed.
Step 203, the transmitting range of signal of the uplink signal of user terminal is set as the satellite wave accessed with itself
The reception range of signal of beam is identical.
In a kind of possible realization method, the corresponding range of signal that receives of satellite beams is the corresponding symbol of satellite beams
And/or frequency point.
An example as the present embodiment：
Step 200 can include：User passes through Global Satellite Navigation System (the Global Navigation
Satellite System) position (such as longitude and latitude) of itself is obtained, wherein, Global Satellite Navigation System is included but not
It is limited to following type：GPS (Global Positioning System, global positioning system), BDS (BeiDou
Navigation Satellite System, Chinese Beidou satellite navigation system), GLONASS (GLOBAL NAVIGATION
SATELLITE SYSTEM, GLONASS satellite navigation system) and galileo satellite navigation system (Galileo satellite
navigation system)。
Step 201 can include：From satellite reception broadcast pilot, the star in the user terminal is updated according to broadcast pilot
It goes through.According to the orbital position of the satellite at the ephemeris computation current time.
Wherein, satellite ephemeris is also known as two row orbital datas (TLE, Two-Line Orbital Element), is to be used for
The expression formula of space flight body position and speed is described.Mathematical relationship between 6 orbit parameters of Kepler's law determines
The parameters such as time, coordinate, orientation, the speed of flying body have high precision.User terminal in ground can root
The orbital position of the satellite at current time is calculated according to satellite ephemeris.
Step 202 can include：According to the position of itself, the orbital position of the satellite, calculate user terminal relative to
The azimuth and the elevation angle of satellite.The satellite wave for obtaining user terminal and being accessed is searched in wave beam layout according to azimuth and the elevation angle
The corresponding reception range of signal of beam.
Wherein, antenna beam layout can include the azimuth and face upward that each wave beam is covered in satellite on the star of terminal storage
The angular range at angle.When the azimuth of user terminal, the elevation angle and satellite are in the coverage area of a certain wave beam, it may be determined that should
Wave beam number residing for user terminal, and determine the corresponding reception range of signal of satellite beams that the user terminal is accessed.
Step 203 includes：It is defended what the transmitting range of signal of the uplink signal of user terminal was set as being accessed with itself
The reception range of signal of star wave beam is identical.For example, if user terminal is in the coverage area of the first wave beam, the first wave beam connects
The collection of letters number ranging from first code element, then be set as first code element by the transmitting range of signal of the uplink signal of user terminal.
The disclosure assists implementing beam separation from and utilizing wave beam on star by the global positioning satellite data of user side
The communication performance for coordinating to come effectively to reduce wave beam overlapping region is lost, further lifting system capacity.Meanwhile the disclosure is to system
Expense is small, applied widely, can significantly lifting system in the case where that will not occupy additional time and frequency spectrum resource
Capacity.
As an example of the present embodiment, step 203 further includes：If the number for the satellite beams that user terminal is accessed
It measures as two or more, then the transmitting range of signal of the uplink signal of user terminal can be set as any accessed with itself
The reception range of signal of satellite beams is identical.
For example, if user terminal is simultaneously in the coverage area in the first wave beam and the second wave beam, the reception of the first wave beam
Range of signal is first code element, and the reception range of signal of the second wave beam is second code element, then user terminal may be used first yard
Member or second code element send uplink signal.
It is the application example of satellite communication method below, this method can include：
Step 1：Satellite sends broadcast pilot to user, and broadcast pilot is used for synchronizing to user, and update the star of user side
Go through figure.
Step 2：User side determines present terminal position according to itself GPS signal, is worked as according to the ephemeris computation that satellite issues
Preceding moment satellite orbital position obtains azimuth and the elevation angle of the terminal itself relative to satellite so as to calculate.Then, further according to end
Antenna beam layout on the star of storage is held, the final wave beam number for obtaining terminal access of tabling look-up.
Step 3：User in different access wave beams sends uplink signal using different symbol or frequency point.
Step 4：Each wave beam on satellite receives the uplink signal of user using the symbol or frequency point of setting, specifically
It can include in the following manner：
Mode one：Different beams on satellite receive uplink signal using itself corresponding symbol or frequency point.Due to
Different beams use different symbol or frequency point, interfere and disappear between different beams.
Mode two：Different beams on satellite do not receive uplink signal using only itself corresponding symbol and frequency point,
Signal is received using the symbol or frequency point of closing on wave beam.Then it adjudicates respectively.Inter-beam interference disappears in this case,
And the user of beam selection mistake can also be decoded.In addition, the user in wave beam overlapping region is more due to meeting
A wave beam receives respectively, is obtained with repeatedly adjudicating by decoding respectively, and wave beam overlapping can be reduced by adjudicating to merge
The packet loss of the user in region.
Mode three：Different beams on satellite do not receive uplink signal using only itself corresponding symbol and frequency point,
Signal is received using the symbol or frequency point of closing on wave beam.Then received signal respectively is handled and is made decisions again.
Inter-beam interference disappears in this case, and the user of beam selection mistake can also be decoded.In addition, in wave
The user of beam overlapping region by multiple wave beams due to can respectively be received, and received signal carries out related merging, therefore receives letter
It makes an uproar than can also effectively be promoted, so as to which packet receiving rate can be promoted.
Below in conjunction with specific network structure, to illustrate the workflow of the satellite communication method of the disclosure and specific effect
Fruit.As shown in figure 3, in this network structure, the overlay area of entire satellite communication load is by two wave covers.Wave beam and
The region for having 50% between wave beam is mutually overlapping.Entire overlay area gathers around that there are three users.Wherein user U1 is in the covering of wave beam 1
In region, user U2 is in wave beam crossover region by 2 overlay area of wave beam 1 and wave beam, and user U3 is in the overlay area of wave beam 2
It is interior.Assuming that the signal of the signal of user user under the interference of no other users signal can accurately be connect by satellite
It receives, and a user can be by satellite packet by the signal of the user in the case of the interference of another user.
Application scenarios one：Multiple users send uplink signal simultaneously.
Multiple users send uplink signal simultaneously using identical code word or frequency point.If the same wave beam of satellite receives
Can be interfered with each other during the signal of multiple users, between user leads to packet loss.
As shown in Figure 4：Signal between user U1 and user U2 that wave beam 1 receives is interfering with each other, leads to packet loss.Wave beam
The signal of the 2 user U2 received and user U3 is interfering with each other, leads to packet loss.Therefore in the satellite communication for not using the disclosure
During method, the packet of all users is all lost, packet loss 100%.
If using disclosed method, user can by the GPS signal of satellite ephemeris figure combination user terminal itself
To calculate the wave beam that will be accessed, communicated so as to use different symbols or frequency point.Assuming that user U1 and
User U3 can respectively using symbol c1 and symbol c2 either frequency point f1 and frequency point f2 and user U2 may randomly choose symbol or
Frequency point.It is further assumed that the symbol or frequency point of the selection communication of user U2 are as user U1.
The reception mode of the uplink signal of satellite beams is above-mentioned mode one.As shown in Figure 5：Satellite is receiving signal
When, using symbol c1, either frequency point f1 receives signal to wave beam 1 to receive signal wave beam 2 using symbol c2 or frequency point f2.By
In symbol is orthogonal or frequency orthogonal, wave beam 1 can receive the signal of user U1 and user U2, and wave beam 2 would only receive use
The signal of family U3.Therefore it can accurately be received when occupation mode a period of time, the data of user U3, system packet loss is
66.6%.
The reception mode of the uplink signal of satellite beams is above-mentioned mode two.As shown in Figure 6：Wave beam 1 uses frequency point f1
And either symbol c1 and c2 receives signal and wave beam 2 also uses frequency point f1 and f2 or symbol c1 respectively to f2 respectively
And c2 receives signal respectively, then wave beam 1 can receive the signal of user U1 and user U2.Since the two is interfering with each other, institute
With the whole packet losses of wave beam 1.And wave beam 2 can then be respectively received the signal from user U2 and U3, due to the two symbol or frequency
Point is orthogonal, so not interfering with each other between the two, can be received.Therefore when occupation mode two, system packet loss is
33.3%.
The reception mode of the uplink signal of satellite beams is above-mentioned mode three.As shown in Figure 7：Wave beam 1 is respectively using frequency
Either symbol c1 and c2 receives signal and wave beam 2 also uses frequency point f1 and f2 or code respectively to point f1 and f2 respectively
First c1 and c2 receives signal respectively, and similar with option 2, wave beam 2 can accurately receive the data packet of user U2 and U3.Profit
With the data packet from U2 received by wave beam 2, we can reconstruct the signal of U2 user, then be connect again with wave beam 1
The signal received subtracts the signal of U2, we can extract the signal of user U1, and then the data packet of U1 can also be accurate
It really receives, therefore when occupation mode three, system packet loss is 0.
Application scenarios two：Uplink signal is sent during multiple user's differences.
For example, user U1 and user U2 are sent simultaneously, user U3 is sent at different times, and same wave beam receives multiple use
Can be interfered with each other between user when the signal at family leads to packet loss.
As shown in figure 8, if all users use identical code word or frequency point, user U1 that wave beam 1 receives and
Signal between user U2 is interfering with each other, leads to packet loss.And the user U2 and the signal of user U3 that wave beam 2 receives, each other when
Domain is orthogonal, so the data packet of user U2 and user U3 can be accepted to.Therefore when no use present invention, packet loss
Rate 33.3%.
The reception mode of the uplink signal of satellite beams is above-mentioned mode one.As shown in Figure 9：When receiving signal, wave
Using symbol c1, either frequency point f1 receives signal to beam 1 to receive signal wave beam 2 using symbol c2 or frequency point f2.1 meeting of wave beam
The same symbol of user U1 and user U2 or the signal of frequency point are received simultaneously, signal is interfering with each other, leads to packet loss.And wave beam 2
It would only receive the signal of user U3.Therefore when occupation mode a period of time, the data of user U3 can be received accurately, packet loss
66.6%.
The reception mode of the uplink signal of satellite beams is above-mentioned mode two.As shown in Figure 10：Wave beam 1 is respectively using frequency
Either symbol c1 and c2 receives signal and wave beam 2 also uses frequency point f1 and f2 or code respectively to point f1 and f2 respectively
First c1 and c2 receives signal respectively.Wave beam 1 can receive the signal of user U1 and user U2.Due to user U1 and user U2
Signal it is interfering with each other, so the whole packet losses of wave beam 1.And wave beam 2 can be respectively received the signal from user U2 and U3, due to
The two time domain orthogonal so not interfering with each other between the two, can be received.Therefore using the situation of option 2 of the present invention
Lower packet loss is 33.3%.

Either symbol c1 and c2 receives signal and wave beam 2 also uses frequency point f1 and f2 or code respectively to point f1 and f2 respectively
First c1 and c2 receives signal respectively.It is similar with the mode two of this application scene, wave beam 2 can accurately receive user U2 and
The data packet of U3.Using the data packet from U2 received by wave beam 2, the signal of U2 user can be reconstructed.1 institute of wave beam is used again
The signal received subtracts the signal of U2, can extract the signal of user U1.Then the data packet of U1 can also accurately be connect
It receives, therefore system packet loss is 0.
Application scenarios three：Uplink signal is sent during multiple user's differences.
For example, user U2 and user U3 are sent simultaneously, user U1 using it is different at the time of send, same wave beam receives multiple
Can be interfered with each other between user when the signal of user leads to packet loss.
As shown in figure 12, if all users use identical code word or frequency point, user U1 that wave beam 1 receives and
Signal between user U2 time domain orthogonal each other, can accurately be received.The user U2 and the letter of user U3 that wave beam 2 receives
Number, it is interfering with each other, so the data packet of user U2 and user U3 are by packet loss.Therefore when not using the disclosure, packet loss is
33.3%.
The reception mode of the uplink signal of satellite beams is above-mentioned mode one.As shown in figure 13：When receiving signal, wave
Using symbol c1, either frequency point f1 receives signal to beam 1 to receive signal wave beam 2 using symbol c2 or frequency point f2.Due to code
First orthogonal or frequency orthogonal, wave beam 1 can receive the signal of user U1 and user U2, due to U1 and U2 user time just
It hands over, it is possible to accurately be received.And wave beam 2 would only receive the signal of user U3, it is possible to accurately be received.Therefore it loses
Packet rate is 0.
The reception mode of the uplink signal of satellite beams is above-mentioned mode two.As shown in figure 14：Wave beam 1 is respectively using frequency
Either symbol c1 and c2 receives signal and wave beam 2 also uses frequency point f1 and f2 or code respectively to point f1 and f2 respectively
First c1 and c2 receives signal respectively, then wave beam 1 can receive the signal of user U1 and user U2, due to the two time domain each other
It is orthogonal, so the data that wave beam 1 receives all can be received accurately.And wave beam 2 can be then respectively received from user U2
With the signal of U3, due to the two symbol or frequency orthogonal, so not interfering with each other between the two, can be received.Cause
This uses packet loss 0 in the case of option 2 of the present invention, and since the signal of user U2 can distinguish 2 the inside of wave beam 1 again and wave beam
Adjudicated, therefore the packet loss of the data packet of user U2 can further decline.
The reception mode of the uplink signal of satellite beams is above-mentioned mode three.As shown in figure 15：Wave beam 1 is respectively using frequency
Either symbol c1 and c2 receives signal and wave beam 2 also uses frequency point f1 and f2 or code respectively to point f1 and f2 respectively
First c1 and c2 receives signal respectively.It is similar with the mode two of this application scene, system packet loss 0.Moreover, utilize wave beam 1
The signal of received user U2 and the related merging of the signal of user U2 progress that wave beam 2 is obtained, can effectively improve
User's U2 signal-to-noise ratio, so as to further promote the packet loss of U2.
In conclusion in the case where not using the situation of the disclosure, if the system of user side sends out 9 data packets in total,
4 are accurately received in satellite side, average packet loss ratio 55.5%.After occupation mode one, system can accurately receive 5
A packet, average packet loss ratio 44.4%.After occupation mode two, system can accurately receive 7 packets, and average packet loss ratio is
22.2%.After occupation mode three, system can accurately receive 9 packets, average packet loss ratio 0.In terms of power system capacity angle,
Relative to the situation for not using the disclosure, power system capacity improves 25% after occupation mode one；It is after occupation mode two
It unites capacity boost more than 75%；Power system capacity is improved more than 125% after occupation mode three.It can be seen that the satellite of the disclosure leads to
Communication method can effective lifting system capacity, system reliability is provided.
