Abstract

PURPOSE:To improve the performance of error correction by adding a one parity bit to each word each check word of PCM data to be transmitted. CONSTITUTION:At the output of a parity interleaver 1, PCM data series of 12 channels appear, and words in them are supplied to an encoder 2 one after another to form the 1st check words P12n and Q12n. Further, 12 PCM data series and two check word series are supplied to an interleaver 3. One word each in an output data series of this interleaver 3 is supplied to an encoder 4 to form the 2nd check words R12n and S12n, and a circuit 10 adds a parity bit to each word. This data is applied to the input of en error correcting decoder, and a checker 11 makes a word-by-word parity check. On the basis of a syndrome, a decoder 17 makes an error correction, and a decoder 19 generates an error syndrome by data included in the 1st error correction block and a parity check matrix, thereby correcting the error.
