| 摘要 |
Embodiments of the present invention relate to the communications field, and provide an adaptive modulation and coding method, apparatus, and system, to improve system upgrade flexibility. 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; 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; obtaining a second bit stream according to the second data; modulating the first bit stream and the second bit stream according to a constellation mapping rule; and sending modulated data. The embodiments of the present invention are applicable to a scenario of data processing in mobile communication. |
