Title:
INTERLEAVING AND MODULATION METHOD, APPARATUS, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/098436
Kind Code:
A1
Abstract:
The present application provides an interleaving and modulation method, an apparatus, and a system, used to improve transmission reliability. The method comprises: a transmit end apparatus obtaining bits to be interleaved, and performing first interleaving on the bits to be interleaved to obtain interleaved bits; and modulating the interleaved bits to obtain a modulation symbol, and sending the modulation symbol; and after a receive end apparatus receives the modulation symbol, demodulating and de-interleaving the modulation symbol in a demodulation mode and a de-interleaving mode corresponding to the transmit end to obtain an LLR, and determining an information bit according to the LLR. Wherein, the first interleaving comprises: writing the bits to be interleaved into a first matrix column by column in a first sequence, and reading out the first matrix row by row in a second sequence. The number of columns of the first matrix is a modulation order M, where M is greater than or equal to 3. The first bit read out row by row is an MSB and an Mth bit is an LSB. In an implementation in which M is equal to 3, the first sequence is third column-second column-first column, and the second sequence is first column-second column-third column.
