<p>The present invention relates to a method and an apparatus for encoding/decoding using a sparse inverse code based on a specific density, and the method for encoding comprises: arranging into a first row each bit in original message data by aligning same into an n number of columns, or arranging into a first column each of the bits in the original message data by aligning same into an n number of rows, wherein when the original message data is arranged into the first row and the first column in the first row in which 1 is present is a ith column, components are configured so that a component in a jth column in a j+1th row is 1 and remaining components in the j+1th row are 0, wherein the j satisfies 1≤j＜i for second to the ith rows, and when the component in the jth column in the j+1th row is 0, wherein the j satisfies i＜j≤n, the components are configured so that a component in the jth column in a jth row is 1 and remaining components in the jth row are 0.</p> |
