| 摘要 |
<p>The present invention relates to a feedback apparatus and a data transmission method for network coding. The feedback apparatus for network coding transmits feedback data to a transmission node in response to the reception of a network-coded packet, and includes a feedback data generation part which: accumulates encoding vectors of one or more coded packets received from a transmission node, and generates an encoding matrix; transforms the encoding matrix into a reduced row echelon form matrix; and generates feedback data using the reduced row echelon form matrix.</p> |
