To correct the error on the reception even when the disappearance of data occurs while transmitting by encoding and transmitting the data on the transmission.
When a transfer source data is set to the data of m bits (b0, b1, b2, b3,... bm-1), a data string K=(kn0, kn1, kn2,... knm-1) in n series of m bits is substituted for a simultaneous equation of Boolean algebra b0kn0+b1kn2+...+bm-1knm-1=Pn, and n solutions Pn=(p0, p1, p2, p3,... pn-1) are determined. The packet of the encoded data consisting of the data string K and the solutions Pn is forwarded. In the receiving and decoding step, the data string K and solutions Pn determined from the received encoded data are substituted for the simultaneous equation, and the data of m bits being the transfer source data is decoded.
