Abstract
Embodiments of the present invention provide a method, an apparatus, and a system for interference alignment. The method includes: receiving signals transmitted by transmit ends, where the signals include interference signals and a wanted signal; aligning original constellation diagrams of the interference signals to acquire a first interference aligned constellation diagram; performing, according to the first interference aligned constellation diagram, interference signal demodulation and decoding on the received signals to acquire an interference source bit sequence; performing, according to the interference source bit sequence and the first interference aligned constellation diagram, interference reconstruction and removal to acquire a second interference aligned constellation diagram; and performing, according to the second interference aligned constellation diagram, wanted signal demodulation and decoding on the signal sequence to acquire the wanted signal transmitted by a wanted signal transmit end. The embodiments of the present invention are applicable to radio communications.
