Abstract
A rate matching method allowing reliable digital communication is disclosed. After setting D=|n−m| and Q=n/D, the input symbol string is sequentially divided to produce D symbol strings each consisting of either Q symbols or (Q+1) symbols so as to arrange the input symbols in an arrangement of columns (C) and rows (R). Then, after selecting a single symbol located at a predetermined position for each of the D symbol strings, the output symbol string is provided by deleting the single symbol for each of the D symbol strings when n>m or repeating the single symbol for each of the D symbol strings when n<m.
