RS code-based Zipper code encoding and decoding method

The invention relates to a Zipper code coding and decoding method based on an RS code, and the coding method comprises the steps: 1, obtaining a symbol generated by an information source, and dividing the symbol generated by the information source to obtain information blocks; 2, performing Zipper code coding by taking chunk as a unit, and putting information blocks into information bits of a real part of the current chunk in rows; step 3, updating the imaginary part of the current chunk by mapping the real part of the component code of the previously coded chunk according to a mapping relation phi-1; step 4, coding each row of component codes of the current chunk after the imaginary part is updated by using an RS code encoder to obtain a corresponding check symbol; step 5, putting a verification symbol into a verification position of a component code corresponding to the current chunk; and step 6, repeating the steps 2-5 to complete coding of the current chunk. According to the coding and decoding method pro
