Abstract: This application provides an information transmission method and an apparatus. In the method, a sending device sends a first bit sequence to a receiving device. Optionally, the first bit sequence is an information bit sequence, or the first bit sequence is an information bit sequence obtained through first encoding. The sending device receives a second bit sequence from the receiving device. The sending device sends a first code block to the receiving device, where the first code block is obtained based on a first error pattern and a first check matrix. The first error pattern is determined based on the second bit sequence and the first bit sequence.

Abstract: The present disclosure provides example coding method, apparatus, and computer-readable storage medium. One example method includes sorting a plurality of pieces of run-length encoding (RLE) data based on their distribution probabilities. The plurality of pieces of sorted RLE data are mapped onto a plurality of pieces of reassembled data. The plurality of pieces of reassembled data are expanded into a plurality of pieces of binary data. A first matrix is generated based on the plurality of pieces of binary data. A code sequence is determined by processing a source signal, where the code sequence comprises a first set and a second set. A first vector is decoded to output a third set, where the third set includes one or more bits reserved after processing the source signal and one or more locations at which a decoding error occurs in one or more bits discarded after processing the source signal.
