Abstract
In this paper LDPC encoding algorithms are presented, and the algorithms are analyzed based on CMMB standard by simulation. The performances of the encoding algorithms are compared in terms of decomposition effect and hardware implementation. The simulation results show that the LU decomposition based algorithm which finds the principal components in the row and column with the lightest weight can achieve high decomposition efficiency and is suitable for hardware implementation.
