Description

Wireless communication system based on multiple carriers and communication method thereof
Technical Field
The application relates to the technical field of data communication, in particular to a wireless communication system based on multiple carriers and a communication method thereof.
Background
A carrier wave is a radio wave of a specific frequency that carries data. In wireless communication, the frequency of data to be transmitted is usually low frequency, and if the data is transmitted according to the frequency of the data itself, the reception and synchronization are not facilitated. Using carrier transmission, the signal loading of data can be modulated onto the signal of a high frequency carrier. The receiver receives the data signal according to the carrier frequency, and extracts the required data signal through the difference of the wave amplitudes.
In data communication technology, the use of multi-carrier modulation, i.e. the use of multiple carrier signals (dividing the channel into several orthogonal sub-channels), converts the data signal to be transmitted into parallel low-speed sub-data streams (the sub-data streams have a much lower transmission bit rate), and then modulates the data signal to be transmitted on each sub-channel, i.e. the use of these sub-data to modulate several carriers, respectively, is a reliable way to achieve fast data transmission.
In the prior art, how to use multiple carriers to implement communication is a common technical means, but how to ensure stability of data transmission during multiple carrier communication, that is, whether to perform stable data transmission and identification between devices that need communication is also an important technical point, when the situation cannot be quickly and effectively clarified, efficiency of multiple carrier communication between devices will be discounted, and advantages of multiple carrier data transmission cannot be maximized, so that the application discloses a wireless communication system based on multiple carriers and a communication method thereof.
