Coding method, decoding method and equipment

Abstract

The embodiment of the invention discloses a coding method, a decoding method and equipment, which are used for reducing the bit error rate so as to ensure the system performance when the external noise is relatively large. The coding method comprises the steps that: K second bit blocks with preset lengths are generated according to a first bit block, bits of the first bit block are filled with first effective information, bits of each second bit block are filled with a set of second effective information, K sets of second effective information corresponding to the K second bit blocks form the first effective information, and, in addition, each second bit block is also filled with redundant information; then, the K second bit blocks are coded respectively, K code words are obtained, and any code word in the K code words comprises bit information in one second bit block and verification information corresponding to the bit information; and finally the K code words are modulated and then are sent. The bit error rate can be reduced due to the fact that the number of redundant information in each code word of K is large.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to an encoding method, a decoding method, and a device. Background technique [0002] With the development of communication technology, Ethernet network standards are constantly updated, and the target bearer rate is also continuously increased accordingly. [0003] Existing networking standards define encoding schemes that allow a single cable of a specific length to achieve a target bear rate. For example, one network standard defines a coding scheme for a 100m single cable to achieve 5Gbps when the background noise does not exceed -150dBm / Hz; another network standard defines a 100m single cable A coding scheme that achieves 10Gbps over a single cable. Regardless of the network standard, the coding scheme includes: after receiving the data block, the physical coding PCS sublayer constructs a bit block with a length corresponding to the c...

[0004] However, this encoding method is only suitable for a single cable with a certain background noise. When there is EMC interference outside, or when multiple cables are bundled and used to generate crosstalk between lines, the background noise will increase. To maintain the target bearer rate, the bit error rate will increase and the system performance will decrease
