Title:
DATA TRANSMISSION METHOD AND APPARATUS, AND DEVICE, SYSTEM AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/015863
Kind Code:
A1
Abstract:
A data transmission method and apparatus, and a device, a system and a readable storage medium. The data transmission method comprises: a first module acquiring first data, wherein the first data is data which is encoded by using a first FEC pattern and has been subjected to first processing, and the first processing comprises interleaving processing (201); the first module encoding the first data according to a second FEC pattern, so as to obtain a plurality of second codewords (202); the first module performing second processing on the plurality of second codewords, so as to obtain second data (203); and the first module transmitting the second data (204). By means of the method, transmitted data can have a higher encoding gain by means of concatenated encoding; when data is transmitted in a channel in which a bit error easily occurs, error correction can be effectively performed on data in which a bit error occurs; and since first data is data obtained by means of interleaving processing, the correlation of erroneous bits in a codeword after second FEC can be eliminated, thereby improving the error correction performance and further improving the quality of data transmission.
