Interleaving realizing method and interleaving realizing equipment

Abstract

The invention provides an interleaving realizing method and interleaving realizing equipment. The method comprises the steps that data to be interleaved are input into each interleaving chain in sequence; in each interleaving chain, the input data are written in a storage position pointed by a writing pointer; when the data need to be read out, the data in a position pointed by a reading pointer in each interleaving chain are read out in sequence according to an output sequence value; and the writing pointer points at the next data writing position after the data are written into each interleaving chain, and the reading pointer points at the next data reading position after the data are read out. By adopting the interleaving realizing method and the interleaving realizing equipment provided by the embodiment of the invention, rates of equipment at the two ends of an interleaver can be matched by the interleaver.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method and equipment for realizing interleaving. Background technique [0002] In modern communication systems, the forward error correction coder can correct a certain range of random errors, but in some sudden continuous noise scenarios, the length of the error bit string is likely to exceed the correction rate of the forward error correction coder. scope. At this time, an interleaver can be used to disperse consecutive bits into non-sequential bits, so that longer error bit strings become shorter error bit strings, which can continue to be corrected by the forward error correction encoder. [0003] There are two types of interleavers: block interleaver and convolutional interleaver. For the convolutional interleaver, the input end of the convolutional interleaver inputs the data to be processed into I branches in order for delay processing, and I is the number of branche...
