Problems solved by technology

[0003] In related technologies, RS codes are widely used to carry FEC. However, the complexity of the RS coding algorithm is high, and the circuit logic scale is relatively large. If one codec is used for each service, the overall circuit logic scale will be reduced. Too large, the cost of chip tape-out is too high, so the single-channel RS codec can no longer meet the needs of applications, and an RS codec that supports parallel access to multiple services is needed
[0004] However, the RS code is a block code, and a code word is a complete and indivisible whole
The rate of each business is different, so its multiplexing method has its own particularity. In addition, RS coding and decoding is an intermediate link in the processing flow of bearer network nodes. The delay is fixed, and the output data envelope is required to be uniform. Therefore, at this stage, it is not possible to provide an RS coding and decoding scheme that supports parallel access of multiple services.

Abstract

The invention discloses a coding and decoding method and system, and relates to the technical field of communication. The method comprises the following steps: a plurality of independent channels arebuilt, and each channel is enabled to correspond to a cache space; each channel receives the data frame and caches the data frame to the corresponding cache space; according to a preset scheduling strategy, transmission and coding and decoding of the data frames in each cache space are completed in one cache space at a time, wherein the transmission and coding and decoding of the data frame comprise the steps of reading the data frame in a cache space, transmitting the data frame to an RS coder-decoder, completing the coding and decoding work of the data frame in the cache space, and obtaininga coded and decoded data frame. According to the method disclosed in the invention, coding and decoding work can be carried out on multi-channel data, and various work requirements at the present stage are met.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a coding and decoding method and system. Background technique [0002] As the bandwidth capacity of the 5G bearer network increases, the types of services and the number of access channels of FlexE, FlexO, and OTUk increase. The transmission of various services requires the support of FEC to ensure reliable transmission. [0003] In related technologies, RS codes are widely used to carry FEC. However, the complexity of the RS coding algorithm is high, and the circuit logic scale is relatively large. If one codec is used for each service, the overall circuit logic scale will be reduced. If it is too large, the cost of chip tape-out is too high. Therefore, a single-channel RS codec can no longer meet the application requirements, and an RS codec that supports parallel access to multiple services is needed. [0004] However, the RS code is a block code, and a codewor...
