Abstract

The invention provides a data processing method coded and decoded by FEC, and a relative device. The method comprises: carrying out FEC coding on a FEC code processing sub-layer for a data code block sequence which is output by a physical code sub-layer and uses m data code blocks as a group, to generate n FEC check code blocks; respecitively distributing m*t2 data code blocks and n*t2 FEC check code blocks to M virtual channels of a first virtual channel group and N virtual channels of a second virtual channel group, wherein m*t2 is less than or equal to m_max, m_max is t1 times of M, n is less than or equal to n_max, n_max is t1 times of N, and m, n, t1 and t2 are positive integers; and respectively multiplexing data distributed to the first virtual channel group and the second virtual channel group onto at most H interfaces of a fisrt physical channel group and at most K interfaces of a second physical channel group according to bit speed-changing multiplexing, wherein M is integral multiple times of H, and N is integral multiple times of K.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a data processing method and a related device for FEC encoding and decoding. Background technique [0002] Forward Error Correction (FEC, Forward Error Correction) codec technology is a technology used in communication systems to improve transmission system performance. The use of FEC requires the introduction of FEC encoding and decoding algorithms and processing devices at the source and sink ends of the transmission system, and the additional transmission of verification overhead data generated by FEC encoding at the source end in the transmission system. In a typical single-channel communication transmission system, the transmission of original information data and FEC verification overhead data is mainly realized by increasing the line transmission rate. For example, in a typical RS(255,239), the original 239-byte information is increased to 255 byte...
