Data Processing Method and Apparatus

A method, comprising:

• obtaining a data stream, and performing forward error correction (FEC) coding on the data stream;
• obtaining, by segmenting a data stream obtained according to the FEC coding, a data stream that comprises a plurality of sub-data stream segments;
• performing segment interleaving on the data stream that comprises the plurality of sub-data stream segments, wherein the segment interleaving comprises re-sorting a location of each sub-data stream segment in the data stream that comprises the plurality of sub-data stream segments, and wherein an order of data in each sub-data stream segment in the data stream obtained according to the segment interleaving remains unchanged;
• and
• sending a data stream obtained according to the segment interleaving.

An apparatus, comprising:

• a de-interleaver configured to perform first equalization processing on a data stream that comprises a plurality of sub-data stream segments, and further configured to perform segment de-interleaving on a data stream obtained according to the first equalization processing;
• a decoder configured to separately perform first forward error correction (FEC) decoding on each sub-data stream segment in a data stream obtained according to the segment de-interleaving;
• an equalizer configured to perform, according to an equalization termination state of each sub-data stream segment obtained according to the first equalization processing, second equalization processing on each sub-data stream segment obtained according to the first FEC decoding, and further configured to perform, using the decoder, second FEC decoding on the data stream obtained according to the second equalization processing performed on each sub-data stream segment;
• a processor;
• and
• a non-transitory computer readable medium having a program stored thereon for execution by the processor, the program having instructions to perform at least one of:
• output the data stream obtained according to the second FEC decoding in response to a preset iteration termination condition being met;
• or
• perform, in response to the preset iteration termination condition not being met, according to the equalization termination state of each sub-data stream segment obtained according to the first equalization, the second equalization processing on each sub-data stream segment obtained according to the second FEC decoding.

An apparatus, comprising

• a transceiver, configured to obtain a data stream;
• a coder, configured to perform forward error correction (FEC) coding on the data stream;
• a processor;
• a non-transitory computer readable medium having a program stored thereon for execution by the processor, the program having instructions to:
• obtain, by segmenting a data stream obtained according to the FEC coding, a data stream comprising a plurality of sub-data stream segments;
• and
• an interleaver, configured to:
• perform segment interleaving on the data stream that comprises the plurality of sub-data stream segments, wherein the segment interleaving comprises re-sorting a location of each sub-data stream segment in the data stream that comprises the plurality of sub-data stream segments, and an order of data in each sub-data stream segment in the data stream obtained after the segment interleaving remains unchanged;
• and
• send, using the transceiver, a data stream obtained according to the segment interleaving.
