Abstract
A constellation rotation method is presented. The method includes: determining a statistical characteristic of a received signal of a Base Station (BS) according to a channel coefficient of one or more User Equipments (UEs), at least one of noise information and interference information, the received signal being a signal received by the BS through a physical channel from the one or more UEs; determining a constellation rotation angle of each UE according to the determined statistical characteristic of the received signal; and for each UE, rotating a constellation of a data stream of a UE according to the constellation rotation angle of the UE.
