| 摘要 |
Embodiments of the present invention relate to the field of communications. Provided are an adaptive coding and modulation method, apparatus and system, used for improving flexibility of system upgrade. The method comprises: obtaining data to be processed; obtaining channel information corresponding to the data to be processed, and determining a modulation mode according to the channel information; determining first data and second data from the data to be processed according to the modulation mode; obtaining a first bit stream by performing soft-decision forward error correction (FEC) coding on the first data; 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 apply to a data processing scenario in mobile communication. |
