Abstract

PURPOSE:To prevent the error occurrence due to the overlap reception of the data without increasing the information quantity by setting the odd and even numbers alternately for the sequence of the parity to be added to the data in case the data is transmitted. CONSTITUTION:In case the data No. m, m+1, m+2 and so on are transmitted to the receiver side from the transmitter side, parity P is added to each of the data. This parity P is set alternately to odd, even and odd in that order for arrangement to the data from No. m through No. m+1, m+2 and so on. Then the data given from the transmitter side is set to data buffer 1 at the receiver side, and the signals of buffer 1 are applied to parity decoder 2 to decide the odd and even numbers of parity P. And the result of the decision is given to memory 4, and the odd and even numbers of parity P are checked alternately through parity check 3. And in case parity P features the fixed order, gate 6 is opened; while gate 6 is closed in the case of the overlapped order to inhibit the data transmission.
