Abstract
PURPOSE:To realize high correcting capability with a decoder of a simple constitution, by discriminating the error location at the pointer at the decoder of the next stage for correction. CONSTITUTION:The decoding of the 1st stage is made to the 2nd error correction block, and the PCM data series of a plurality of channels and the 1st check word series are delayed by different time. After that, the decoding of the next stage to the 1st error correction block is made, and at the decoding of the 1st stage, the error having the number of words K or less in the 2nd error correction block is made, and when the error is detected exceeding the number of words, all the words in the block are regarded including error and the error presence pointer is added to each word. At the decoding of the next stage, if the pointer of the words M or less in the 1st error correction block represents error, this is judged as the error location, and the error word of a given number is corrected by using the error location and error syndrome.
