Technical Field
The invention belongs to the technical field of communication, and particularly relates to a signal transmission method based on characteristics and related information.
Background
In a conventional wireless communication system, after signal source coding, channel modulation, and the like are performed on a signal, the signal is transmitted to a wireless channel for transmission, and then channel demodulation, channel decoding, signal source decoding, and the like are performed at a receiving end to recover the signal transmitted by a transmitting end.
Due to the unreliable wireless communication link transmission, the failure of signal transmission is easily caused, and the receiving party cannot receive correct signals. Therefore, in the wireless transmission process, the system adopts a great number of means for ensuring the transmission reliability or transmission efficiency. Particularly, as the information (message, voice, image or video, etc.) to be transmitted becomes more complex, the transmission processing of the existing wireless communication system becomes more complex, various coding and decoding techniques and modulation and demodulation techniques with high complexity emerge endlessly, and the wireless transmission system becomes more complex.
In fact, in some specific application scenarios, some processing means can be used to obtain the characteristics of the message, voice, image or video, etc. that need to be transmitted, and then only the characteristic information, not all the information, is transmitted in the wireless transmission, and is recovered at the receiving end, although some performance may be sacrificed, unexpected other effects can be obtained.

The invention aims to solve the problem of how to make the transmission of a wireless communication system simpler and quicker.
The technical scheme of the invention is as follows:
a method for a wireless communication system based on transmission of only characteristic and related information, comprising the steps of:
signal transmission:
s1, extracting data feature information of data to be sent by a feature extraction method aiming at the data to be sent;
s2, inquiring a corresponding mapping relation from a source association database based on the data characteristic information, wherein the source association database stores the sending data of the history, the data characteristic information of the sending data, and the mapping relation between the sending data and the data characteristic information; if the mapping relation can not be inquired, generating the current mapping relation and updating the source association database;
s3, coding and modulating the data characteristic information in the S1 and the mapping relation in the S2 as sending signals, and then sending the signals through a sending end;
signal receiving:
s4, after receiving the signal, the receiving end demodulates the signal to obtain the data characteristic information and the mapping relation;
s5, inquiring the host association database based on the data characteristic information, judging whether the data characteristic information is stored in the host association database, if so, entering the step S6, otherwise, repeating the step S5 after carrying out data synchronization on the host association database and the source association database;
and S6, extracting the received data from the sink association database based on the received data characteristic information and the mapping relation.
The invention has the beneficial effects that: in some application scenarios, the processes of encryption, decryption, coding, decoding and modulation and demodulation in wireless transmission can be greatly simplified, and the transmission reliability can be better ensured.
