Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for transmitting a wide-narrow beam signal, and an electronic device.
Background
The relay user terminal mainly uses a reflector antenna and a helical antenna to be matched with a relay satellite system to complete the space-based measurement and control task. The Ka/S dual-band reflector antenna is a narrow-beam antenna, is the earliest relay antenna and is mainly used for daily measurement and control; the S-band helical antenna is a wide-beam antenna, is applied later than a reflector antenna in the relay field, is fixedly installed, does not need to be issued in advance to control the antenna to point to a relay satellite, and is mainly used for emergency measurement and control.
When a spacecraft is designed, the technical states of a wide beam and a narrow beam are often expected to be consistent or similar, the wide beam and the narrow beam select the same frequency, and the spread spectrum codes are different, so that the spacecraft is similar to code division multiple access; but at the same time, the space mission often only uses one of the wide beam or the narrow beam according to the requirement, and the mode is similar to time-sharing use. The cdma system needs to control the power of different spread spectrum signals, but due to different data rates of wide and narrow beams, different antenna gains, and other reasons, the difference of the transmission power is large, and a signal mislocking situation may occur. That is, when the space mission only uses the narrow beam link, the wide beam link receiving channel may erroneously lock the signal due to the high level of the narrow beam signal, and demodulate data with a large amount of error codes, thereby causing confusion of data interpretation.

Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The narrow beam antenna has large volume and is relatively difficult to install, and particularly, the payload of an individual spacecraft or other equipment occupies the opposite sky surface of the spacecraft, so that the narrow beam antenna can only be installed in a biased mode, and the coverage range of the relay satellite is influenced; meanwhile, the narrow beam antenna has a low rotation speed, and sometimes cannot continuously point to the relay satellite when the attitude of the spacecraft is changed rapidly, so that a link is interrupted. Although the wide-beam antenna is named as a wide beam, the coverage range of the beam is about 60 degrees at most due to the fixed installation of the antenna, and the coverage range of the relay satellite is influenced due to the defect of the upper half plane (90 degrees). In order to expand the coverage range of the relay satellite, a wide beam antenna and a narrow beam antenna can be simultaneously installed on a spacecraft, a wide beam link and a narrow beam link are established, and multi-routing reliable transmission of remote measurement and control data is realized.
In practical operation, the wide-beam and narrow-beam links usually use S-band signals, and S-band mutual interference is easy to occur. In order to solve or avoid interference, multiple access techniques such as time division multiple access, frequency division multiple access, code division multiple access, etc. are generally used. However, in practical applications, there is still a problem that the signal is erroneously locked and the error data is demodulated. Based on this, the method, the device and the electronic device for transmitting the wide and narrow beam signals provided by the embodiments of the present invention can alleviate the problem that error data is demodulated due to signal error locking in the wide and narrow beam link communication, and improve the wide and narrow beam link communication effect.
For the convenience of understanding the present embodiment, a detailed description will be first given of a method for transmitting a wide-and-narrow-beam signal disclosed in the present embodiment.
The first embodiment is as follows:
as shown in fig. 1, a flowchart of a method for transmitting a wide-narrow beam signal according to an embodiment of the present invention is applied to a receiving end, and as shown in fig. 1, the method includes the following steps:
step S102: receiving a communication signal; the communication signal is a wide beam signal and/or a narrow beam signal.
And receiving the communication signal by a receiving end, wherein the receiving end can be a ground receiving station, a ground mobile end or a spacecraft and a communication satellite end.
The received communication signal may be either or both of a wide beam signal and a narrow beam signal. That is, a single wide beam signal or a single narrow beam signal may be received to implement communication; or the receiving of the main beam signal and the narrow beam signal can be performed simultaneously, and the two signals are jointly used to realize communication. Therefore, the receiving end may have only a wide beam signal receiving channel or a narrow beam signal receiving channel, or both channels.
The wide beam signal is transmitted from a wide beam antenna, and the narrow beam signal is transmitted from a narrow beam antenna. The narrow beam antenna refers to an antenna with a small beam width of a radiation pattern, and can effectively overcome multipath and co-channel interference in communication.
Step S104: a bit signal-to-noise ratio of the communication signal is calculated.
Here, the bit snr refers to a ratio of signal energy to noise energy in one bit period, which is used to characterize the quality of a wireless channel, as well as a general snr. In this embodiment, the bit error rate is counted first, and then the bit snr is estimated by using the corresponding curve of the snr and the bit error rate.
The bit signal-to-noise ratio of the received communication signal, whether it is a wide beam signal or a narrow beam signal or both, is calculated, and for the case where the wide beam signal and the narrow beam signal are received, the bit signal-to-noise ratios of the two are calculated, respectively.
Step S106: and when the frame synchronization of the communication signal is detected, judging whether the communication signal of the frame synchronization is correctly locked or not according to the bit signal-to-noise ratio.
Here, in a digital time division multiplexing communication system, in order to correctly separate each time slot signal, a start flag for each frame must be provided at a transmitting end, and a process of detecting and acquiring this flag at a receiving end is called frame synchronization. In actual operation, a receiving end receives signals, and the signals are subjected to carrier locking, decoding synchronization and then frame synchronization. When a signal is frame-synchronized, the signal is generally considered to be locked, but when a receiving end simultaneously has a wide beam signal receiving channel and a narrow beam signal receiving channel, and a transmitting end only uses a narrow beam link, the narrow beam signal level is high, the wide beam link receiving channel may erroneously lock the signal, and demodulate data with a large number of error codes, which further causes confusion of data interpretation, and therefore, frame synchronization is not equivalent to correct signal locking.
In practice, it is found that when the signal is in a wrong lock state, the bit signal-to-noise ratio estimation result of the receiving end is obviously reduced, therefore, whether the signal is correctly locked is judged according to the bit signal-to-noise ratio Eb/No of the received signal, and whether the communication signal is correctly locked is further judged by combining the bit signal-to-noise ratio of the communication signal with frame synchronization.
Here, in one embodiment, the bit snr of the frame-synchronized communication signal may be compared with a preset bit snr threshold; if the signal-to-noise ratio is larger than the bit signal-to-noise ratio threshold value, the frame synchronization communication signal is judged to be correctly locked.
In practical operation, it is found that when the signal is in error lock, the bit snr estimation result at the receiving end is reduced by more than about 10 dB. Therefore, the bit snr threshold can be set according to the bit snr when the signal is normally received, and the difference between the bit snr threshold and the bit snr when the signal is normally received can be controlled within 10 dB.
Step S108: if yes, outputting the demodulation data of the frame synchronization communication signal.
When the bit signal-to-noise ratio of the frame-synchronized communication signal is also greater than the preset bit signal-to-noise ratio threshold, it is determined that the communication signal is correctly locked, and at this time, the communication signal can be demodulated and its demodulated data can be output.
In another possible implementation, when the receiving end receives the wide beam signal and the narrow beam signal, and both signals are frame-synchronized and their respective bit signal-to-noise ratios meet the requirement, it is necessary to compare the signal locking times of the wide beam signal and the narrow beam signal and output the demodulated data of the signal with the earlier signal locking time.
In addition, for the case that the receiving end has both the wide beam signal receiving channel a and the narrow beam signal receiving channel B, when the signal frame of the signal receiving channel a (B) is out of step or the bit snr thereof is lower than the preset threshold, and the signal receiving channel a (B) is outputting the demodulated data, if the signal receiving channel B (a) determines that the signal locking is correct at this time, the signal receiving channel a (B) stops demodulating the data, and the signal receiving channel B (a) outputs the demodulated data.
Therefore, in the wide and narrow beam link communication process, before the demodulated data is output by the demodulated signal, the frame synchronization signal is further judged according to the bit signal to noise ratio of the received signal, so that the accuracy of signal locking is further improved, and the problem that error code data is demodulated due to signal error locking in the wide and narrow beam link communication is effectively solved.
The embodiment of the invention provides a wide and narrow beam signal transmission method, which is applied to a receiving end and comprises the steps of receiving a communication signal; the communication signal is a wide beam signal and/or a narrow beam signal; calculating a bit signal-to-noise ratio of the communication signal; when the frame synchronization of the communication signal is detected, judging whether the frame-synchronized communication signal is correctly locked or not according to the bit signal-to-noise ratio; if yes, outputting the demodulation data of the frame synchronization communication signal. According to the method, when signal frames are synchronized, whether the signals are correctly locked or not is judged according to the signal-to-noise ratio of the received signals, and the demodulated data is output only when the signals are correctly locked, so that the problem that error code data are demodulated due to the fact that the signals are incorrectly locked in the wide-narrow beam link communication can be solved, and the wide-narrow beam link communication effect is improved.
Example two:
the embodiment of the invention introduces a wide and narrow beam signal transmission method, which shows communication interaction between a sending end and a receiving end.
Referring to fig. 2, a schematic flow chart of a method for transmitting a wide-narrow beam signal according to an embodiment of the present invention is shown in fig. 2, where the method includes the following steps:
step S202: a sending end sends a communication signal; the communication signal is a wide beam signal and/or a narrow beam signal.
Here, the transmitting end may transmit either one of a wide beam signal, a narrow beam signal, or both.
Step S204: the receiving end receives the communication signal.
Step S206: the receiving end calculates the bit signal-to-noise ratio of the communication signal.
Step S208: when the receiving end detects the frame synchronization of the communication signal, whether the communication signal of the frame synchronization is correctly locked is judged according to the bit signal-to-noise ratio.
Here, the bit snr of the frame-synchronized communication signal may be compared with a preset bit snr threshold; if the signal-to-noise ratio is larger than the bit signal-to-noise ratio threshold value, the frame synchronization communication signal is judged to be correctly locked.
Step S210: if yes, outputting the demodulation data of the frame synchronization communication signal.
If the frame synchronization signal is judged to be correctly locked through the bit signal-to-noise ratio of the frame synchronization signal, the frame synchronization signal is demodulated and demodulated data of the frame synchronization signal is output. Otherwise, the frame synchronization signal is not demodulated.
The wide-narrow beam signal transmission method provided by the second embodiment of the present invention has the same technical characteristics as the wide-narrow beam signal transmission method provided by the first embodiment, so that the same technical problems can be solved, and the same technical effects can be achieved.
Example three:
referring to fig. 3, another method for transmitting a wide-beam and narrow-beam signal according to an embodiment of the present invention is applied to a transmitting end, where the transmitting end includes a wide-beam signal transmitting channel and a narrow-beam signal transmitting channel, as shown in fig. 3, the method includes the following steps:
step S302: and acquiring data to be transmitted.
Step S304: and judging whether the data to be transmitted is key data or not.
Here, according to actual application requirements, a user may set some types of data as key data, for example, when data to be transmitted belongs to measurement and control data, it is determined that the data to be transmitted belongs to key telemetry data or complete telemetry data, so that different signal transmission channels are selected for transmission under different conditions.
Step S306: if so, selecting a wide beam signal sending channel to send the data to be transmitted, so that a receiving end outputs the demodulated data of the wide beam signal when receiving the wide beam signal of the data to be transmitted and judging the signal to be correctly locked according to the bit signal-to-noise ratio of the wide beam signal.
Here, for the above example of measurement and control data, when data to be transmitted is key telemetry data, a wide beam signal transmission channel is selected to transmit the data, and here, because the wide beam transmission EIRP (Effective Isotropic Radiated Power) is significantly lower than the narrow beam, the transmission rate of the wide beam is also reduced.
Step S308: if not, selecting a narrow beam signal sending channel to send the data to be transmitted, so that a receiving end outputs demodulation data of the narrow beam signal when receiving the narrow beam signal of the data to be transmitted and judging the signal to be correctly locked according to the bit signal-to-noise ratio of the narrow beam signal.
If the data to be transmitted is not the key data, a narrow beam signal transmitting channel can be selected to transmit the data to be transmitted, and when a receiving end receives the narrow beam signal of the data to be transmitted and judges that the signal is correctly locked according to the bit signal-to-noise ratio of the narrow beam signal, the demodulated data of the narrow beam signal is output.
