Abstract: Embodiments of this application disclose a modulation method. A first communication apparatus generates a first symbol stream based on a symbol type quantity, a probability distribution corresponding to a first symbol of each symbol type, a bit quantity corresponding to each first symbol, and a first original bit stream, the bit quantity corresponding to each first symbol is a bit quantity required by each first symbol that is represented by using a bit, and first symbols of different symbol types correspond to different probability distributions and/or different signal amplitudes; and the first communication apparatus generates a first quadrature amplitude modulation (QAM) symbol stream based on the first symbol stream and a second original bit stream.
