Data processing method and data processing apparatus

A data processing apparatus, comprising at least one processor and a transceiver, wherein the transceiver is configured to perform data sending and receiving operations, and the at least one processor is configured to:

• perform probabilistic constellation shaping (PCS) processing on a first bit set in k bits, to obtain a second bit set, wherein k is an integer greater than 1;
• perform forward error correction (FEC) encoding on the second bit set and a third bit set in the k bits excluding the first bit set, to obtain a fourth bit set, wherein the fourth bit set comprises m0 first bit subsets, each of the first bit subsets comprises F0 bits, m0 is an integer greater than 1, m0=12 or 16, and F0 is an even number greater than 1;
• and
• perform first interleaving processing on the fourth bit set to obtain a fifth bit set, wherein the fifth bit set comprises m0 second bit subsets, each of the second bit subsets comprises F0 bits,
• F
• 0
• 2
• bits in each of the second bit subsets are from the second bit set, and the other
• F
• 0
• 2
• bits in each of the second bit subsets are from at least one of the third bit set or parity bits of the FEC encoding.
