The embodiment of the invention provides a data transmission method based on UWB multiple antennas, and an execution subject of the data transmission method based on UWB multiple antennas can be the audio transmission equipment provided by the embodiment of the invention.
As shown in fig. 1, fig. 1 is a schematic flow chart of a data transmission method based on UWB multi-antenna according to an embodiment of the present invention, and the specific flow of the data transmission method based on UWB multi-antenna may be as follows:
101. and generating test data when the terminal invokes the UWB antenna to transmit and receive target data.
The data transmission method based on the UWB multi-antenna provided by the embodiment of the application is based on UWB (Ultra Wide Band) technology, and the UWB technology has the advantages of low system complexity, low power spectrum density of a transmitting signal, insensitivity to channel fading, low interception capability, high positioning accuracy and the like, and is particularly suitable for high-speed wireless access in indoor and other dense multipath places. Therefore, the device connected by the method provided by the application can bring high-order, fidelity and low-delay audio wireless transmission due to the adoption of UWB ultra-wideband technology.
In an embodiment, the UWB antenna of the terminal device to which the method is applied includes a plurality of transmitting antennas and a plurality of receiving antennas, and when the terminal invokes the UWB multi-antenna to transmit and receive the target data, test data can be generated first to test the plurality of transmitting antennas and the plurality of receiving antennas, so as to determine the target antenna with higher transmission quality. Specifically, a part of the target data can be intercepted to form a data packet as test data, so that the data volume can be reduced, and the subsequent test speed can be improved. In other embodiments, the corresponding test data may be generated according to the target data, for example, when the target data is an audio file, an audio demo may be generated as the test data.
102. And controlling the plurality of transmitting antennas to sequentially transmit test data to the plurality of receiving antennas respectively.
In one embodiment, the UWB TX transmission module of the terminal may carry N transmit antennas, labeled tx_1, tx_ … … tx_n, respectively. The orientations of the antennas are different, and the antennas cover different directions of the environment in an omni-directional manner, so that the transmitting end realizes the omni-directional perception of the transmission environment. Accordingly, the UWB RX transmission module is also equipped with N receive antennas, labeled rx_1, rx_ … … rx_n, respectively. The orientation of these receive antennas corresponds to the transmit end and also covers all directions of the environment in an omni-directional manner. Such a design ensures that the system is also able to sense the transmission environment in all directions during the reception phase.
Further, by combining the tx_1, tx_ … … tx_n and rx_1, rx_ … … rx_n antennas, the same test data packet can be controlled to be sequentially transmitted from tx_1 to rx_1, and from rx_2 … … rx_n to rx_1, and from tx_2 to rx_2 … … rx_n, the same test data packet can be sequentially transmitted from tx_n to rx_1, and from rx_2 … … rx_n, until the same test data packet is sequentially transmitted from tx_n to rx_1, and the receiving end can transmit a response to the transmitting end after receiving the complete test data and checking the complete test data, so as to ensure the integrity of the whole data transmission.
103. And counting the integrity information and the delay information of all transmission paths aiming at the test data respectively.
After the test data on all the transmission paths are sent, the integrity information and the delay information of all the transmission paths for the test data can be counted so as to further select the transmission path with the best signal quality. The integrity information may be compared with the data packets before and after the test data is transmitted in each transmission path. The delay information may then be calculated by testing the transmit time stamp and the receive time stamp of the data packet on the current transmission path.
In an embodiment, besides evaluating signal quality through the integrity information and the delay information, network transmission rate information on each transmission path may be obtained, where the network transmission rate refers to a rate of transmitting test data on a digital channel, and a plurality of ways may be used to obtain a current network transmission rate of each transmission path, and specifically, the current network transmission rate may be calculated according to a size and a transmission time of a test data packet. For example, the receiving end antenna may receive a test data packet (such as a video or a music) sent by the sending end antenna, record the time of receiving the data packet, and divide the data size and time to obtain the current network transmission rate.
In another embodiment, since the signal quality received by the antenna with high signal strength is better than the signal quality received by the antenna with low signal strength, the signal strength of each transmission path when the receiving end antenna receives the test data packet can be obtained, and the optimal transmission path can be selected together by combining the above integrity information, delay information, network transmission rate and other parameters.
104. And selecting a target transmitting antenna and a target receiving antenna according to the integrity information and the delay information so as to transmit and receive target data through the target transmitting antenna and the target receiving antenna.
In one embodiment, referring to fig. 2, an app control encoder (encoder) generates test packets and transmits the test packets to rx_1 and rx_ … … rx_n controlled by a receiver unit (receiver unit) through tx_1 and tx_ … … tx_n controlled by a transmitter unit (transmitter unit), respectively, and the test packets can be decoded by a decoder (decoder).
Wherein each data transmission is performed sequentially by different antenna combinations of Tx and Rx. Taking tx_1 as an example, it would be combined with rx_1, rx_ … … rx_n in order to form a plurality of different antenna transmission paths, which is not just a strategy to provide diversity for more efficient data transmission. During the process of sending data multiple times, we can accurately record the integrity information and delay information of each path. The system-level data collection enables us to know the performances of different antenna combinations in practical application, so as to select an optimal transmission path, determine a target transmitting antenna and a target receiving antenna corresponding to the optimal path, and transmit and receive target data through the target transmitting antenna and the target receiving antenna.
The dynamic selection mechanism provided by embodiments of the present application not only considers integrity information, but also focuses on delay levels, and the system will tend to preferentially select those antenna combinations that have exhibited higher integrity and low delay in the past. The dynamic selection mechanism enables the system to flexibly select the optimal antenna combination in each transmission, thereby reducing the probability of the signal being influenced by the obstacle and further improving the overall transmission quality.
It should be noted that the electronic device may be any device capable of LTE communication, for example: a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop Computer), a personal digital assistant (personal digital assistant, PDA for short), a mobile internet Device (Mobile Internet Device, MID) or a Wearable Device (wearmable Device), etc.
In this way, according to the data transmission method based on UWB multiple antennas provided by the embodiments of the present invention, when the terminal invokes UWB antenna to transmit and receive target data, test data is generated, multiple transmitting antennas are controlled to sequentially transmit the test data to multiple receiving antennas, integrity information and delay information of all transmission paths for the test data are counted, and target transmitting antennas and target receiving antennas are selected according to the integrity information and the delay information, so as to transmit and receive target data through the target transmitting antennas and the target receiving antennas. The scheme provided by the embodiment of the application introduces a plurality of transmitting and receiving antennas, so that the optimal antenna combination can be dynamically selected according to the integrity information and the delay information of the test data so as to transmit and receive target data, the possibility of signal interference can be reduced, and the antenna performance is improved.
The method according to the previous embodiments will be described in further detail below.
Referring to fig. 3, fig. 3 is a schematic diagram of a second flow chart of a data transmission method based on UWB multi-antenna according to an embodiment of the present invention. The method comprises the following steps:
201. and when the terminal invokes the UWB antenna to transmit and receive the target data, acquiring the type and the data volume information of the target data.
202. And generating test data according to the type and the data volume information.
In an embodiment, the UWB antenna of the terminal device to which the method is applied includes a plurality of transmitting antennas and a plurality of receiving antennas, and when the terminal invokes the UWB multi-antenna to transmit and receive the target data, test data can be generated first to test the plurality of transmitting antennas and the plurality of receiving antennas, so as to determine the target antenna with higher transmission quality. Specifically, the type of the target data and the data volume information can be used for generating corresponding test data, the test data can be generated through real-time calculation, and the test data can also be directly obtained from a database, for example, a data packet which is the same as the type of the target data but has a smaller data volume is searched in the database to be used as the test data.
203. And controlling the plurality of transmitting antennas to sequentially transmit test data to the plurality of receiving antennas respectively.
For example, the antennas tx_1, tx_ … … tx_n and rx_1, rx_ … … rx_n are combined, and specifically, the antennas tx_1 can be controlled to sequentially transmit the same test data packet to rx_1, rx_ … … rx_n, tx_2 can sequentially transmit the same test data packet to rx_1, rx_ … … rx_n, and so on, until tx_n sequentially transmits the same test data packet to rx_1, rx_ … … rx_n.
204. And counting the integrity information and the delay information of all transmission paths aiming at the test data respectively.
In an embodiment, after the test data on all the transmission paths are sent, the integrity information and the delay information of all the transmission paths for the test data can be counted. The delay information can be calculated by testing the sending time stamp and the receiving time stamp of the data packet on the current transmission path. The integrity information may further include the integrity and the bit error rate before and after the data transmission, that is, the step of counting the integrity information of all transmission paths for the test data may include: and acquiring the integrity and the error rate of all the transmission paths respectively aiming at the test data before and after transmission, and calculating the integrity information of the transmission paths according to the integrity and the error rate.
In one embodiment, the bit error rate (SER: symbol error rate) is an indicator of the accuracy of data transmission over a specified period of time, where bit error rate = 100% of the number of errors in transmission/total number of codes transmitted, and if there is an error, there is a bit error rate. In addition, bit error rate is defined as a measure of how often the bit error occurs.
205. And determining the weight values corresponding to the integrity information and the delay information, and calculating the quality scores of all transmission paths according to the weight values.
206. And selecting a target transmission path with the highest quality score, and determining a target transmitting antenna and a target receiving antenna corresponding to the target transmission path so as to transmit and receive target data.
In an embodiment, the path with the best transmission quality can be selected through the integrity information and the delay information, and considering that the priority of the integrity information and the priority of the delay information are different, for example, the integrity information is more important than the delay information, so that the weight values corresponding to the integrity information and the delay information can be determined, then the respective quality scores of all the transmission paths are calculated according to the weight values, and finally the target transmission path with the highest quality score is selected, and the target transmitting antenna and the target receiving antenna corresponding to the target transmission path are determined, so as to transmit and receive the target data.
In another embodiment, the lowest delay path may also be selected from the 100% integrity transmission paths as the target transmission path. For example, a path with 100% integrity before and after transmission of the test data packet among all transmission paths is determined first as an alternative path, and then a target transmission path with the lowest delay is selected from the alternative paths.
In an embodiment, the step of transceiving the target data through the target transmitting antenna and the target receiving antenna may include: and adjusting the transmitting power of the target transmitting antenna according to the signal intensity when the target receiving antenna receives the test data, so as to control the target transmitting antenna and the target receiving antenna to transmit and receive the target data through the adjusted transmitting power.
In an embodiment, if there is a transmission path with failed transmission of test data, the transmission power of the corresponding transmitting antenna may be further increased to retransmit the test data, and the retransmission number is counted, and when the retransmission number is greater than a preset value and still fails to transmit, the data transmission of the current transmission path may be stopped and error reporting information may be output.
The increasing the transmitting power of the antenna may include various methods, such as multiple increasing according to fixed increasing, or may be increased in a jumping manner, or may be directly increased to the rated maximum power of the current antenna, etc.
For example, if the initial transmit power of the antenna is 15dBm and the rated maximum transmit power is 40dBm, and if no response information returned by the receiving end is received within a preset period after the data packet is transmitted at the initial power, the transmit power of the antenna may be gradually increased until the transmit power is increased to 40dBm, or may be directly increased to 40dBm at a time. It should be noted that, after increasing the transmitting power of the antenna each time, it is required to determine whether the response information returned by the receiving end is received within a preset period of time, if not, the transmitting power of the antenna is continuously increased until the maximum power.
When the transmitting power of the transmitting antenna is increased to the maximum power, judging whether response information returned by the receiving end is received, if not, retransmitting at the maximum power value all the time, and counting the retransmission times.
