The error detection device and method of the signal part which between mutual is put the receiver and the decoding method of adopting the said error detection

(57) Abstract The error detector and method of detection and that error detection which do the error detection of the mutual between signal part which includes the n continual data byte which consists of with the information data byte group and at least the error detection data byte of 1 bytes adoption it is decoding method. The error detector operates, in order to form the syndrome which shows whether or not error was detected with the mutual between signal part. The syndrome which occurs formed is the same syndrome as the former error detector which does the error detection of the mutual dissociation signal part which corresponds with dissociation of the mutual between signal part. As for the error method of detection which this error detector uses: Being maximum (a) (as the quantity of between the data bytes which use m for the formation of the mutual between signal part) pulling out m flow of the continual data byte from the n data byte which it receives at the data byte of continual m group, as it includes the data byte where each data bytes style differ in the respective n data byte, the data bytes style of j turn eye in m flow that to try include the byte of j turn eye from each group j as the integer which becomes 0jm, (b) from m data bytes style m part syndrome to form, (c) the m partOn the basis of syndrome, as for the receiver and the decoding method of adopting this error method of detection which forms the last syndrome which shows whether or not error was detected to the mutual between signal part, as advantage of the error detector is enjoyed, (a) error detection (b) it becomes possible to do simultaneously with the mutual dissociation of the mutual between signal part.
