Description

Technical Field

[0001] This application relates to the field of wireless communication, and in particular to a method, system, apparatus and medium for wireless communication. Background Technology

[0002] With the rapid development of Chinese society, communication systems are becoming increasingly complex. Wireless optical communication, which propagates information through space without requiring optical fibers or frequency licenses, offers greater flexibility compared to fiber optic and microwave communication, making it suitable for specialized communication scenarios. Modulation and demodulation technology is a crucial component of optical communication, and its reliability directly impacts the performance of the entire communication system.

[0003] In a communication system, the analog signal is converted into a set of digital pulse signals at the information acquisition end. Pulse Position Modulation (PPM) encoding is used to encode the digital pulses into pulse information. A single laser transmits the encoded pulses. At the receiving end, the signal is decoded to recover the original signal, completing the information transmission. The L-PPM encoding method is used in the information encoding stage. This method maps n-bit binary bits to 2... n In a PPM symbol composed of multiple information time slots, a single laser is used to transmit pulse information simultaneously. When using a single laser to transmit pulse information obtained by single-pulse modulation, the number of transmitted bits is relatively small, the bandwidth utilization is low, resulting in a longer time required to complete a certain amount of data, low data transmission efficiency, and weak anti-interference capability.

[0052] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0053] The core of this application is to provide a wireless communication method, system, apparatus, and medium for improving data transmission efficiency.

[0054] In a communication system, analog signals are converted into a set of digital pulse signals at the information acquisition end. These digital pulses are then encoded using single-pulse PPM modulation to form pulse information. A single laser transmits the encoded pulses, and at the receiving end, the signal is decoded to recover the original signal, completing the information transmission. However, because single-pulse pulse position modulation is used, the data transmission efficiency is low, the bandwidth utilization is low, and the anti-interference capability is weak. Therefore, this application employs multi-pulse position modulation (MPPM). The larger the number of pulses, the more binary information stream this method can transmit, resulting in stronger signal transmission capability. Furthermore, by having multiple lasers transmit pulse information in turn, the problems of low transmission efficiency and low transmission code rate of a single laser are solved.

[0055] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Figure 1 A flowchart illustrating a wireless communication method applied at a transmitting end, as provided in an embodiment of this application, is shown below. Figure 1 As shown, the method includes:

[0056] S10: Obtain the data to be sent and package the data into a network data frame;

[0057] S11: Perform multi-pulse position modulation on the network data frame to acquire multiple pulse signals;

[0058] S12: Pulse signals are sent to the receiving end through multiple lasers so that the receiving end can demodulate the pulse signals and receive the data to be sent.

[0059] When the sending end and the receiving end are communicating wirelessly, the sending end needs to send data to the receiving end. When acquiring data to be sent, the sending end can read data packets transmitted from other network devices (routers, switches, video encoders, etc.) and then package the data into network data frames.

[0060] After acquiring network data frames, MPPM modulation is performed on them. The working principle of MPPM modulation is to map n-bit binary blocks onto an MPPM symbol composed of M information time slots according to a certain rule. In each MPPM symbol, at least two of the M information time slots contain signal optical pulses, while the other time slots do not. For example, using (7,4) PPM multi-pulse modulation, during the modulation process, five consecutive binary signals are modulated onto a time period consisting of seven time slots. The optical pulses appear in four time slots, and these four pulses are arranged according to a certain pattern, thus completing the modulation of (7,4) PPM pulses. Simultaneously with modulation, a system reset signal and a system clock signal can also be provided.

[0061] After acquiring multiple pulse signals, if a single laser is used to transmit the pulse signals, the data transmission rate will be low. Therefore, in this embodiment, multiple lasers are used to transmit the pulse signals. The number of lasers selected is not limited and is determined based on the actual situation. Preferably, the number of lasers selected is determined according to the number of pulse signals to be transmitted; that is, the number of pulse signals equals the number of lasers. For example, if the number of pulse signals to be transmitted is four, then four lasers can be selected to transmit one pulse signal each.

[0062] After the transmitter sends out a pulse signal, it is received by the receiver. The receiver needs to demodulate the received pulse signal to obtain the data sent by the transmitter.

[0063] The wireless communication method provided in this embodiment is applied at the transmitting end. The method includes: acquiring data to be transmitted and packaging the data into network data frames; performing multi-pulse position modulation on the network data frames to obtain multiple pulse signals; and transmitting the pulse signals to the receiving end via multiple lasers, so that the receiving end can demodulate the pulse signals and receive the data to be transmitted. Compared to the previous method of using single-pulse position modulation to obtain a single pulse signal and transmitting that single pulse signal via a single laser, the method provided in this embodiment uses multi-pulse position modulation at the data transmitting end to obtain multiple pulse signals and transmits the pulse signals via multiple lasers. This relatively increases the amount of data transmitted, reduces the time required to complete a certain amount of data transmission, greatly improves data transmission efficiency, and relatively enhances anti-interference capabilities.

[0064] To obtain network data frames, a preferred implementation involves obtaining the data to be sent and packaging it into network data frames, including:

[0065] Get the data to be sent;

[0066] The data to be sent is compressed and encoded using a video or audio encoder;

[0067] Acquire the processed data and send it to the network card;

[0068] The network interface card (NIC) packages the processed data into network data frames, which include at least the processed data, a frame header, and a CRC checksum.

[0069] Data is collected at the sending end, and the data and information are compressed and encoded using a video or audio encoder. The data is then packaged and converted into machine-readable data before being sent to the network card.

[0070] A network interface card (NIC) provides a pathway for data exchange between a host and a network. This involves two main aspects: At the sending end, it reads data packets transmitted from other network devices (routers, switches, video encoders, etc.), packages the data into network data frames, adds frame headers and cyclic redundancy check (CRC) checksums, and finally sends the packaged data frames over the network. At the receiving end, it unpacks the data, transforming it into data that the client or server can recognize, and transmits the data to the required device (Central Processing Unit (CPU), memory, or hard drive) via the motherboard bus. Upon receiving, the NIC decodes the received data packets, removes frame headers and trailers, performs CRC checks, and then extracts the data. Figure 2 A schematic diagram of a network data frame provided in an embodiment of this application, as shown below. Figure 2As shown, a network data frame consists of at least the data to be sent, a frame header, and a CRC checksum.

[0071] In this embodiment, when acquiring data to be sent and packaging it into network data frames, the data is compressed and encoded to reduce the amount of data transmitted. Furthermore, the network data frames contain checksums to verify whether data loss or errors have occurred during transmission, thus ensuring the accuracy of data transmission.

[0072] In implementation, network data frames may require multiple MPPM modulations. A preferred implementation involves performing multi-pulse position modulation on the network data frames to acquire multiple pulse signals, including:

[0073] Multi-pulse pulse position modulation is applied to network data frames;

[0074] Obtain the number of subframes before multi-pulse pulse position modulation;

[0075] Increment the number of subframes before multi-pulse pulse position modulation by 1 to obtain the number of current subframes;

[0076] Determine if the number of current subframes is equal to the length of the network data frame;

[0077] If so, then the process ends;

[0078] If not, return to the step of performing multi-pulse pulse modulation on the network data frame.

[0079] Figure 3 A flowchart illustrating a method for modulating network data frames using (7, 4) MPPM, as provided in an embodiment of this application. Figure 3 As shown, the method includes:

[0080] S13: Add a 16-bit frame synchronization header;

[0081] S14: Add superframe length;

[0082] S15: Modulate the input sequence using (7, 4) MPPM;

[0083] S16: Increment the subframe counter by 1;

[0084] S17: Determine if the number of subframes is equal to the superframe length; if not, return to step S15; if yes, proceed to step S18.

[0085] S18: Clear subframe calculator to 0;

[0086] S19: Error detection.

[0087] Therefore, in this method, by counting subframes, when the number of subframes equals the superframe length, it indicates that the data in the network data frame has been modulated, and thus the subframe counter is cleared to 0; when the number of subframes does not equal the superframe length, it indicates that the data in the network data frame has not been modulated, and thus the process returns to step S15 to modulate the subframes until the number of subframes equals the superframe length. The (7, 4) MPPM modulation method is used in wireless communication systems. As the number of pulses increases, this method can transmit more binary information streams, resulting in stronger transmission capabilities.

[0088] To detect whether errors have occurred in the data of the modulated network data frame, a preferred embodiment, when it is determined that the number of subframes equals the length of the network data frame, further includes the following wireless communication method:

[0089] Acquire each subframe after pulse position modulation;

[0090] Perform CRC check on each subframe.

[0091] The determination of whether the modulation of network data frames is complete provided in this embodiment can ensure that the data to be sent can be completely transmitted as much as possible. In addition, when it is determined that the data to be sent has been completely modulated, the accuracy of the modulated data can be determined by CRC check, so as to ensure that the receiving end can receive the correct data as much as possible.

[0092] After MPPM modulation, multiple pulse signals are obtained. To improve data transmission efficiency, a preferred embodiment involves sending the pulse signals to the receiving end via multiple lasers, including:

[0093] Obtain the number of pulse signals in a frame of data obtained after multi-pulse pulse position modulation;

[0094] Each pulse signal is sent to the receiving end by a laser with the same number of pulses.

[0095] The number of lasers transmitting pulse signals is not limited and is determined based on the actual situation. For example, in the (7,4) MPPM modulation used above, since there are 4 pulses in one frame of data after (7,4) MPPM modulation, four laser arrays can be used to work sequentially in a loop, with each laser emitting one pulse. One cycle transmits one subframe, completing the signal transmission. After (7,4) MPPM modulation, the four lasers take turns transmitting pulse information, solving the problems of low transmission efficiency and low transmission code rate of a single laser. It should be noted that just as there is a laser for transmitting data at the transmitting end, there is a laser for receiving data at the receiving end, using an optical detector for signal reception.

[0096] The method provided in this embodiment, which sends each pulse signal to the receiving end using a laser with the same number of pulses as the pulse quantity, can improve the efficiency of data transmission to the receiving end.

[0097] Based on the above embodiments, this embodiment also provides a wireless communication method applied at a receiving end. The wireless communication method includes:

[0098] The system acquires multiple pulse signals transmitted by the transmitting end; these pulse signals are obtained by the transmitting end acquiring the data to be transmitted and packaging the data into network data frames; and by performing multi-pulse position modulation on the network data frames.

[0099] The pulse signal is demodulated and the data to be transmitted is obtained.

[0100] Figure 4 A flowchart of a (7, 4) MPPM demodulation method provided for embodiments of this application is shown below. Figure 4 As shown, the method includes:

[0101] S20: 16-bit frame synchronization detected;

[0102] S21: Determine if the superframe length is between 64 bits and 1518 bits; if not, return to step S20; if yes, proceed to step S22.

[0103] S22: Demodulate the received data;

[0104] S23: Determine whether the superframe has been received successfully; if not, return to step S22; if yes, proceed to step S24.

[0105] S24: Error detection and handling.

[0106] Therefore, if it is determined that the superframe is not completed, the method continues to demodulate the received data to ensure that the receiving end receives complete data. In addition, CRC check is performed on the demodulated data to verify the accuracy of the data received by the receiving end.

[0107] The wireless communication method applied to the receiving end has corresponding technical features as the wireless communication method applied to the transmitting end described above. The wireless communication method applied to the transmitting end has been described in detail above. Therefore, the embodiments of the wireless communication method applied to the receiving end will not be repeated here, and it has the same beneficial effects as the wireless communication method applied to the transmitting end mentioned above.
