Generates an irregular parity check matrix that is used by MT LDPC Encoder for LDPC encoding. In this node, the number of ones in each column is kept constant, and the number of ones in each row is random.
maximum number of iterations
The maximum number of iterations to return a parity check matrix that is not rank deficient.
The number of columns in the parity check matrix.
The number of rows in the irregular parity check matrix.
The number of ones in the columns of LDPC code. j must be an odd number.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Default: no error
