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.
