Data Processing Method and Related Apparatus

A data processing apparatus:

• a memory configured to store instructions;
• and
• a processor coupled to the memory, wherein when executed by the processor, the instructions cause the data processing apparatus to:
• obtain an encoded data frame that is based on first forward error correction (FEC) encoding, wherein the encoded data frame comprises v bits, and wherein v is an integer greater than 1;
• obtain a first bit set based on the encoded data frame and dpad padding bits, wherein a quantity of bits in the first bit set is v+dpad bits, and wherein dpad is an integer greater than or equal to 1;
• perform convolutional interleaving on the first bit set to obtain a second bit set;
• and
• perform second FEC encoding on the second bit set to obtain a third bit set,
• wherein the third bit set comprises R codewords,
• wherein each codeword in the R codewords comprises K information bits and N−K parity bits,
• wherein R, N, and K are integers greater than 1,
• wherein v+dpad=R×K, and
• wherein dpad when divided by K returns a non-zero remainder.

A computer program product comprising computer-executable instructions that are stored on a non-transitory computer-readable medium and that, when executed by a processor, cause a data processing apparatus to:

• obtain an encoded data frame that is based on first forward error correction (FEC) encoding, wherein the encoded data frame comprises v bits, and wherein v is an integer greater than 1;
• obtain a first bit set based on the encoded data frame and dpad padding bits, wherein a quantity of bits in the first bit set is v+dpad bits, and wherein dpad is an integer greater than or equal to 1;
• perform convolutional interleaving on the first bit set to obtain a second bit set;
• and
• perform second FEC encoding on the second bit set to obtain a third bit set,
• wherein the third bit set comprises R codewords,
• wherein each codeword in the R codewords comprises K information bits and N−K parity bits that total N bits,
• wherein R, N, and K are integers greater than 1,
• wherein the v+dpad=R×K, and
• wherein dpad when divided by K returns a non-zero remainder.
