Information interleaving method, information de-interleaving method, and related device

Abstract

The invention provides an information interleaving method, an information de-interleaving method and a related device. The information interleaving method comprises the steps: obtaining an original bit of target information, wherein the original bit is corresponding to an original bit sequence of the target information; adding at least one wildcard character to an interleaving model used for scrambling the sequence of the original bits, wherein at least one wildcard character does not serve as a starting input position and an ending input position of the interleaving model; inputting the original bit into the interleaving model added with the wildcard characters; and obtaining scrambling bits of the target information outputted by the interleaving model after the wildcard characters are added, wherein the scrambling bits are corresponding to a bit sequence of target information scrambling. According to the interleaving method disclosed by the invention, the distance of adjacent bits before interleaving can be disordered after interleaving, so that higher resistance to a burst error resistance is realized. Besides, in the scheme of the invention, only wildcard characters are added to the original interleaving model, so that the scheme is low in execution complexity, does not occupy processing resources, and has very high practicability.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information interleaving method, an information deinterleaving method and related devices. Background technique [0002] Interleaving coding is a communication technology to improve the fading of mobile communication signals in the actual mobile communication environment. It will cause sudden errors in digital signal transmission, and the use of interleaving coding technology can disperse and correct such sudden errors, and improve the transmission characteristics of mobile communications. [0003] The purpose of interleaving coding is to discretize a longer burst error into random errors, and then use random error correction coding (FEC) technology to eliminate random errors. The greater the interleaving depth, the greater the dispersion and the stronger the ability to resist burst errors. However, the greater the interleaving depth, the longer the interleavi...

AI Technical Summary

Problems solved by technology

However, the current block interleaver has poor randomness and cannot change the interval between any two bits in the original information, so the ability to resist burst errors is very limited.

[0005] Of course, the above-mentioned block interleaver is only used as an example. The interleaving method of other interleaving models is the same as that of the block interleaver, and the above-mentioned problems will also exist.
