Performs LDPC encoding on the input bit stream based on the parity check matrix. The parity check matrix can be generated by MT LDPC Generate Regular Parity Check Matrix, MT LDPC Generate Irregular Parity Check Matrix, or you can provide it as an input to MT LDPC Encoder.
parity check matrix in
The sparse parity check matrix generated by MT LDPC Generate Regular Parity Check Matrix or MT LDPC Generate Irregular Parity Check Matrix. You can also set a parity check matrix that is not rank deficient in this parameter.
input bit stream
The incoming bit stream to be mapped to LDPC symbols.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Default: no error
A Boolean that determines whether the internal state of the encoder is cleared.
Clears any buffered bits from previous iterations.
Continues encoding from the previous iteration. Any buffered bits from the previous iteration are added to the beginning of the input bit stream prior to encoding.
parity check matrix out
The preprocessed parity check matrix that is used by the encoder for encoding. You must provide this parity check matrix to the decoder.
output bit stream
Bit sequence encoded by this node.
The encoder places the generated parity bits at the end of the output bit stream array by default. Hence, the encoded word format is [ message bits | parity bits ].
