Problems solved by technology

However, the existing data frame structure requires the load to be absolutely consistent in rate, and the frame length is not variable. When the load rate and frame length in the channel change, it will cause serious errors in data transmission at the modulation end, which directly affects the load information. take over

Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] The present invention adopts a brand-new data superframe structure to realize the combination of information frame rate and data stream with frame length constantly changing: firstly, the mode information of each information frame in the data superframe is intelligently stored in the signaling frame, and then Intelligent framing based on frame mode information. If the carrier rate changes, add the corresponding frame header information before the changed frame; if the mode information indicates that only the load rate changes, select the corresponding clock; if only the frame length changes, directly add the variable-length frame to the superframe.

[0019] A method for generating a data superframe of an adaptive transmission channel, comprising the following steps:

[0020] (1) After inserting the start of the current data superframe in the current f...

Abstract

The invention discloses a method for generating a data superframe of an adaptive transmission channel, which is particularly suitable for the actual demodulation application of the adaptive transmission channel with a variable frame-by-frame rate. The method stores the mode information of each information frame of the next data superframe in the current signaling frame, the start and end frame numbers corresponding to the same mode information frame, and the information corresponding to the current carrier rate when the carrier rate changes. After the frame framing is completed, the frame header and information frame of the next carrier rate are added, which can realize real-time and accurate demodulation and decoding of the adaptive transmission channel with variable frame rate.

Description

technical field [0001] The invention relates to a method for generating a data superframe structure of an adaptive transmission channel, and is particularly suitable for the practical application of a modulation and demodulation system adopting frame-by-frame rate-variable adaptive coding and modulation technology. Background technique [0002] In the link adopting the frame-by-frame rate-variable adaptive coding and modulation technology, the mode information (rate, coding mode and modulation mode) of the payload data to be sent is different according to the link requirements. However, the existing data frame structure requires the load to be absolutely consistent in rate, and the frame length is not variable. When the load rate and frame length in the channel change, it will cause serious errors in data transmission at the modulation end, which directly affects the load information. take over. Therefore, how to correctly combine the data stream with changing information f...
