摘要： Embodiments relate to the communications field, and provide an adaptive modulation and coding method, apparatus, and system. The method includes: obtaining to-be-processed data; obtaining channel information corresponding to the to-be-processed data, and determining a modulation mode according to the channel information. The method also includes determining first data and second data from the to-be-processed data according to the modulation mode; performing soft decision forward error correction FEC coding on the first data to obtain a first bit stream. The method also includes obtaining a second bit stream according to the second data, and modulating the first bit stream and the second bit stream according to a constellation mapping rule; and sending modulated data.
