A communication method and apparatus
By performing distribution matching and channel coding on the information bits, the energy of the check sequence is prioritized to correspond to the symbol bit of the modulation symbol. This solves the problem of low decoding performance of existing LDPC codes in high-throughput scenarios or peak rates, and achieves higher transmission reliability and decoding performance.

AI Technical Summary
Technical Problem
Existing LDPC codes fail to effectively protect low-reliability bits in high-throughput or peak-rate scenarios, resulting in low decoding performance and reduced transmission reliability.
Method used
By performing distribution matching and channel coding on the information bits, priority is given to ensuring that the energy of the check sequence is higher, so that it corresponds to the symbol bit of the modulation symbol, thereby improving the reliability of the check sequence and enhancing the transmission reliability in high-throughput scenarios or peak rates.
Benefits of technology
It improves decoding performance and transmission reliability in high-throughput scenarios or peak rates, and enhances the effectiveness of channel coding.
