====================================
Implementation Details
The Forward Error Correction (FEC) Encoder element performs linear encoding (linear block code) of the input signal using a user defined generator matrix.
The generator matrix file must be formatted using the alist format [1]. If only the parity-check matrix is available, the script command ‘constructgeneratormatrix’ will attempt to create the correspondent systematic generator matrix. The generator matrix should follow the standard form, where the identity matrix is at the beginning of the matrix.
For more details of this element, please visit the page Forward Error Correction (FEC).
