METHOD FOR PRODUCING AND DECODING OF ERROR CORRECTING CODE, AND APPARATUS THEREOF

摘要

PURPOSE: A method for producing and decoding an error correcting code and an apparatus thereof are provided to perform encryption by using an error correcting code in a data transmitting process in a satellite communication system. CONSTITUTION: A asymmetric matrix is generated by adding a column and/or a row consisting of zero bits to a matrix(110). Primary coding is performed by adding parity bits to the row of the asymmetric matrix consisting of data bits and the zero bits(130). Secondary coding is performed by adding the parity bits to each row of the encoded matrix in the primary encoding(150). The column and/or the row of the added zero beat are deleted from an asymmetric matrix generating step in the encoded matrix(170).
