Symbol is added the superposition constellation formed.The user that channel condition is good can segment constellation, the most first demodulates the first constellation and (uses
s2Represent), then delete s2Second constellation (is used s1Represent) interference, re-demodulation s1；The use of bad channel conditions
Family is only capable of rough segmentation constellation, is i.e. only capable of demodulating s2, owing to channel condition is poor, it is impossible to differentiate further and recover s1。
For being similar to the superposition constellation of Figure 13, the power of the first constellation is relatively big, and two use can demodulate per family, the
The power of two constellations is less, and the user that only channel condition is good has the ability to demodulate.It is required to blind in view of two users
Completing subsequent demodulation on the premise of inspection is correct, when using constellation blind check in superposition constellation, transmitting terminal can first carry out two
Level constellation superposition, then converts superposition constellation to obtain conversion constellation.
In the present embodiment, transmitting terminal determine carry out constellation conversion in the case of can also be to only the first constellation being carried out
