Abstract: A coding method for data communication is provided, and may be applied to a plurality of scenarios such as a metro network, a backbone network, and a data center interconnection. The method includes: forming a first codeword, where the first codeword includes n image bits and n to-be-transmitted bits, the n image bits are selected from to-be-transmitted bits in m source codewords, the source codeword is a codeword formed before the first codeword, both n and m are positive integers, and n>m; and sending the n to-be-transmitted bits in the first codeword. The bit in the first codeword is protected by a plurality of codewords generated at different moments, and a coding gain effect is better. In addition, the bit in the codeword is protected by different quantities of codewords.

Abstract: A data processing method includes the following operations: separately performing convolutional interleaving on n lane data streams to obtain n first data streams, where n>1, and first FEC encoding is performed on all the n lane data streams. Every a codewords obtained through the first FEC encoding are distributed in b lane data streams, where a≤b≤n, and a≥1. z consecutive symbols in each of the first data streams are from z different codewords, and z>1. Then, every K first data streams of the n first data streams are multiplexed to obtain one second data stream, so as to obtain a total of m second data streams. The n first data streams include G first data stream subsets, symbols in different first data stream subsets are from different codewords, m=n/K, K>1, and G>1. y consecutive symbols in each second data stream are from y different codewords, where y>z.

Abstract: This application provides a communication method and apparatus. The method includes: encoding a to-be-transmitted first bit sequence to obtain a first matrix, where the first matrix includes a plurality of bit square matrices of a same size, and each bit square matrix includes a plurality of pieces of bit data; performing, based on a first mapping relationship, position transformation in a range of each bit square matrix on the bit data of each bit square matrix in the first matrix, to obtain a second matrix after the position transformation; and performing bit data position transformation among bit square matrices on the second matrix to obtain a third matrix, and modulating a to-be-sent first symbol sequence based on the third matrix.
