Abstract
Embodiments of the present application disclose a modulation method, including: performing coding processing on raw data to obtain a coded sequence; performing constellation mapping on the coded sequence based on a preset constellation diagram, to obtain M symbols; dividing the M symbols into N segments; obtaining a constellation phase of each symbol in the N segments; adjusting a constellation phase of a symbol in each of the N segments according to a preset phase adjustment rule, where the N segments are concurrently adjusted; and modulating M symbols obtained through phase adjustment, to obtain a modulated signal, and sending the modulated signal. Correspondingly, this application further provides a demodulation method, a sending device, a receiving device, and a communications system.
