PHYSICAL LAYER ENCODING AND DECODING METHOD AND APPARATUSES THEREOF

摘要

This application discloses a physical layer encoding and decoding method and apparatuses thereof, where the method includes: receiving an MII control block and a first 256-bit to-be-encoded block that are input; determining a control block in the first 256-bit to-be-encoded block, and compressing the determined control block; determining a physical layer encoding format, a value of a sync header, a hierarchy of a block type field, and a value of the block type field according to the MII control block; and obtaining an encoding result by means of mapping the compressed to-be-encoded block to data in a physical layer data format according to the determined physical layer encoding format, adding a sync header to the data, and adding, according to the hierarchy of the block type field, a block type field to space obtained by compression. This application may be used to meet a requirement of an RS-FEC algorithm.

主权项

1. An encoding method, comprising:
receiving a media independent interface (MII) control block and a first 256-bit to-be-encoded block; determining a control block in the first 256-bit to-be-encoded block according to the MII control block, wherein the determined control block is compressed to obtain a compressed to-be-encoded block; determining a physical layer encoding format, a value of a sync header, a hierarchy of a block type field, and a value of the block type field according to the MII control block; and obtaining an encoding result, the obtaining comprising
mapping the compressed to-be-encoded block to data in a physical layer data format according to the determined physical layer encoding format,adding a sync header to the data, andadding, according to the hierarchy of the block type field, a block type field to space obtained by compression, wherein a value of the added sync header is the determined value of the sync header and a value of the added block type field is the determined value of the block type field.
