Abstract
An embodiment of the present disclosure contemplates a data sending and receiving method and apparatus. A first FEC unit of a sending device sends, by using a first channel, a first data stream on which first FEC encoding has been performed; a second FEC unit of the sending device sends, by using a second channel, a second data stream on which second FEC encoding has been performed; and the sending device performs interleaving on the first data stream and the second data stream, to obtain an output data stream, and sends the output data stream to a receiving device.

A method, comprising:
- generating, by a first Forward Error Code (FEC) encoder, first FEC encoded data;
- generating, by a second FEC encoder, second FEC encoded data;
- generating a plurality of data streams by performing block-level interleaving on the first FEC encoded data and the second FEC encoded data, wherein a number of data streams of the plurality of data streams is 2N and N is a natural number greater than 1, wherein an interleaving granularity of the block-level interleaving is at least two bits, and wherein in each pair of adjacent data streams of the plurality of data streams, data units located at a same position in the data streams of the respective pair comprise a data unit from the first FEC encoded data and a data unit from the second FEC encoded data;
- and
- obtaining at least one interleaved data stream by performing bit-level interleaving on the plurality of data streams, wherein an interleaving granularity of the bit-level interleaving is only one bit, and wherein a number of interleaved data streams of the at least one interleaved data stream is less than 2N.
