PCT No. PCT/JP84/00099 Sec. 371 Date Nov. 7, 1984 Sec. 102(e) Date Nov. 7, 1984 PCT Filed Mar. 12, 1984 PCT Pub. No. WO84/03808 PCT Pub. Date Sep. 27, 1984.There is provided an apparatus for correcting errors in data which has, as a unit, (n+k+m+l) symbols subjected to the processing for the error correction coding when data consisting of different kinds of n symbols and m symbols is transmitted as a unit. This error correcting apparatus comprises: a first decoder to which (n+k) symbols are supplied and which generates a first flag signal indicative of the error state by at least performing the error detection; and a second decoder to which the (n+k) symbols corrected by the first decoder and the (m+l) symbols received are supplied and which generates a second flag signal representing the error state by performing the error detection and performs the error correction using the first and second flag signals. |
