ABSTRACT:
The method and device include determining by removing N−N, rows from an original generator matrix (G) defining the LDPC code and having N rows and N−M columns for obtaining a generator sub-matrix (G1) having N−M columns and N1rows. The method also includes delivering by receiving an input data vector of size N−M and multiplying the input vector with the generator sub-matrix for obtaining the punctured encoded code word.
