摘要

The present invention relates to a network-channel combining coding method, a network-channel combining coding device, and a network that provide an improved error correction function. The method includes dividing a plurality of packets at a transmitting node into a predetermined number of sub-Packet-by-sub-network encoding step of combining the combined sub-packets and generating a packet in which the combined sub-packets are combined by the predetermined number, and encoding the combined packet through a Low Density Parity Check (LDPC) An LDPC encoding step, a first order LDPC decoding step of error-correcting a packet received at the receiving node, an error occurrence position estimating step of estimating an error symbol position in the error-corrected packet at the receiving node, The packet is suted to additional error correction The second comprises a LDPC decoding step.
