<p><P>PROBLEM TO BE SOLVED: To increase a success rate of error correction in a transmission apparatus of an error correction encoding digital signal even when there are many errors in block encoding receiving signals of two systems and error correction is impossible in a conventional method. <P>SOLUTION: In an error correction impossible error correction unit (packet) out of block encoding signal inputs of two systems and more, respective timing phases are made to coincide with each other in each word, error correction is applied to a signal block code regenerated by selecting a signal by a plurality of references in each word, and a system whose error correction has completed is selected. The selection reference is any one of 2N+1, 4N+1, 4N+2, 4N+3, 4N+1 and 4N+2, the first half of two divisions, the first half of four divisions, and the first half of even divisions. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
