Communication method and apparatus

An apparatus, comprising:

• a memory storing instructions;
• and
• at least one processor in communication with a memory storing instructions, the at least one processor configured, upon execution of the instructions, to cause the apparatus to perform the following steps:
• determine, based on N bit sets, a first sequence and a second sequence that are obtained through quadrature amplitude modulation (QAM), the first sequence comprising N in-phase components and the second sequence comprising N quadrature components, or the first sequence comprising N quadrature components and the second sequence comprising N in-phase components, N being an integer greater than or equal to 2, a first symbol is obtained by rotating a second symbol by a first angle on a constellation diagram, the rotation is performed clockwise or counterclockwise using an origin of a constellation diagram as a circle center, and the first angle is greater than or equal to a minimum angle by which a symbol of the second modulation order rotates clockwise or counterclockwise on the constellation diagram when the symbol of the second modulation order encounters the first symbol of the first modulation order;
• perform interleaving processing on the first sequence to obtain a third sequence;
• and
• send, to a receive end device, a symbol sequence determined based on the second sequence and the third sequence, the symbol sequence comprising N QAM symbols.

A non-transitory computer-readable media storing computer instructions that configure at least one processor, upon execution of the instructions, to cause an apparatus comprising the processor to perform the following steps:

• determine, based on N bit sets, a first sequence and a second sequence that are obtained through quadrature amplitude modulation (QAM), the first sequence comprising N in-phase components and the second sequence comprising N quadrature components, or the first sequence comprising N quadrature components and the second sequence comprising N in-phase components, N being an integer greater than or equal to 2, a first symbol is obtained by rotating a second symbol by a first angle on a constellation diagram, the rotation is performed clockwise or counterclockwise using an origin of a constellation diagram as a circle center, and the first angle is greater than or equal to a minimum angle by which a symbol of the second modulation order rotates clockwise or counterclockwise on the constellation diagram when the symbol of the second modulation order encounters the first symbol of the first modulation order;
• perform interleaving processing on the first sequence to obtain a third sequence;
• and
