A method of adaptive transmission to keep data continuous

Abstract

The invention provides a data continuity maintaining method during an adaptive transmission process, aiming for providing a method for maintaining continuity of data transmission when the transmission mode is changed during the adaptive transmission process. The data continuity maintaining method during an adaptive transmission process can be implemented through the technical scheme that: performing carrier wave and bit alignment tracking through a carrier wave and bit alignment tracking module, and determining according to the pre-determined transmission mode through a determination module; performing frame synchronization tracking for the determination result through a frame synchronization module, and sending the data after finishing of frame synchronization to a decoding module; performing error correction and decoding for the received data according to the pre-determined rules by the decoding module, and then sending the decoded data to a transmission mode extraction module; and extracting the modulation mode, the transmission frame size, the encoding mode and other information of the next frame at the corresponding position of the received data by the transmission mode extraction module, and sending the modulation mode, the transmission frame size, the encoding mode and other information of the next frame to the determination module, the frame synchronization module and the decoding module respectively by the transmission mode extraction module so that the data of next frame can be received.

Description

Technical field [0001] The invention relates to an adaptive transmission method suitable for maintaining continuous data reception during the adaptive transmission process in wireless communication. The invention can adapt the modulation mode to switch among 8PSK, QPSK, SQPSK and BPSK. Background technique [0002] Bandwidth and power are the two most important limiting factors in wireless communication. On the one hand, it is hoped to use limited bandwidth resources as much as possible to increase the channel capacity of the system; on the other hand, it is hoped that more information can be transmitted under lower transmission power. The wireless communication channel is different from the wired channel. The condition of the wireless communication channel will be affected by factors such as rainfall, multipath, and changes in the distance between the sending and receiving parties. Traditional wireless communication uses fixed modulation and coding methods to complete the signa...
