A wireless digital communication system

Abstract

The invention discloses a wireless digital communication system, which can improve the communication flexibility of a wireless audio transmission system, improve the resource utilization rate of the system and effectively reduce the power consumption of the system. The wireless digital communication system provided by the embodiment of the invention comprises transmitter equipment and receiver equipment. The transmitter equipment comprises a communication state acquisition unit, a regulation information generation unit and a first frame structure regulation unit, wherein the communication state acquisition unit is used for acquiring communication state indication information; the regulation information generation unit generates frame structure regulation information according to the communication state indication information when learning that a communication state is changed, and transmits the frame structure regulation information to a receiver; and the first frame structure regulation unit regulates a frame structure by utilizing the frame structure regulation information to perform data communication with the receiver. The receiver equipment comprises a regulation information receiving unit and a second frame structure regulation unit, wherein the regulation information receiving unit is used for receiving the frame structure regulation information; and the second frame structure regulation unit regulates the frame structure by utilizing the frame structure regulation information to perform the data communication with a transmitter. The scheme is applied to a plurality of wireless communication systems with relatively higher requirements on transmission quality.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a wireless digital communication system. Background technique [0002] With the advancement of wireless digital transmission technology, especially based on the 2.4GHz frequency band, the appearance of a system-on-chip with low power consumption, low radiation, and low cost has made wireless digital transmission technology widely used in wireless digital audio products. possible. [0003] Currently, wireless digital audio transmission technologies mainly include three types of wireless transmission technologies based on Wireless Fidelity (WiFi), Bluetooth and 2.4G. Among them, the wireless audio transmission technology based on WiFi has the advantages of high bandwidth, but due to the large transmission power of WiFi, it causes problems such as high energy consumption and high radiation; There is a high delay on the Internet; the wireless transmission tec...

[0006] This existing processing method causes a waste of system bandwidth resources and increases system power consumption. For example, the existing wireless audio communication method is only for communication systems in fixed scenarios, and the pre-set frame structure is only applicable to this fixed scene. The communication method of the sending end and the earphone end in the scene is not flexible enough, and when the communication scene changes, the pre-set frame structure may no longer be applicable to the new scene, resulting in the inability to transmit audio data; and the existing frame In the structure, multiple retransmission packets are set for the data packet, and when the data packet is transmitted normally, there is no need to retransmit the data. In this existing processing method, in any case, each frame transmitted includes multiple A retransmission packet not only wastes the bandwidth of the system, but also increases the power consumption of the sending end and the earphone end
