Problems solved by technology

[0004] However, the interleaving technology in the related art randomly selects the position of the interleaved bit, therefore, the bit on the selected position may be a bit that is difficult to recover reliable information, and selecting such a bit is interleaved with the expected continuous error bit, Although it can disperse consecutive error bits, it makes the decoding process after deinterleaving very cumbersome

Abstract

The invention discloses a data processing method and device, and the method comprises: obtaining the expected bit position and length of a continuous error in a to-be-transmitted data block, and enabling the obtained length to serve as a first interleaved bit length; obtaining a bit position capable of recovering information in the to-be-transmitted data block; selecting a bit position with the same length as the first interleaved bit length from the obtained bit positions capable of recovering the information as a target bit position; and interleaving the bits at the bit positions where continuous errors are expected to occur and the bits at the target interleaved bit positions with each other. According to the embodiment of the invention, the target interleaved bit position is a positionwith high information recovery reliability, and the bits at the positions are interleaved with the bits at the bit positions where continuous errors are expected to occur, so that the bits at the bitpositions where the continuous errors are expected to occur are easy to recover information and high in recovery reliability, the subsequent decoding process is simplified, and the decoding overheadis reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of optical communication, and in particular, to a data processing method and device. Background technique [0002] In optical communication systems, channels can be roughly divided into three categories according to the characteristics of bit error distribution: random channels, burst channels, and mixed channels. In a random channel, the transmission errors in the receiving sequence appear randomly, and the error distribution has the characteristics of statistical independence, that is, there is no correlation or the correlation is weak, so a reasonable error correction coding method can be used according to the distribution characteristics of the error code. Resistant to independent random errors. However, in a burst channel, such as a channel of a passive optical network (Passive Optical Network, PON) system, since the upstream channel works in the burst mode, and since the optical ...
