Single encoder and decoder for forward error correction coding
Various embodiments disclosed herein provide for a transmitter that can adjust the size of an information block or segment the information block based on a forward error correction (FEC) code optimum efficiency. Certain FEC codes are more efficient at encoding and decoding longer information blocks and if an information block is shorter than a predetermined length, the transmitter can pad the information block with a group of null bits to lengthen the information block to increase the performance of encoding and decoding the information block. In some embodiments, the transmitter can segment the information block into a set of segments, and if the last segment is below the predetermined length, the transmitter can pad the last segment.
