Abstract: The present invention discloses a signal processing method, apparatus, and system. In M user equipments, an active set Ki and an interference set K′i of a user equipment i are determined according to power measurement values from the user equipment i to N sites; for the active set Ki of the user equipment i, superposition of sent signals of all other user equipments j of all active sites ki are cancelled out with each other, to obtain one constraint condition of a weight, and for the M user equipments, M constraint conditions are obtained, and a weight subspace T is determined; and one weight is determined in the weight subspace according to an interfering signal of another user equipment j for the user equipment i in the interference set K′i of the user equipment i and a wanted signal of the user equipment i in the active set Ki of the user equipment i.
Abstract translation: 本发明公开了一种信号处理方法，装置和系统。 在M个用户设备中，根据从用户设备i到N个站点的功率测量值来确定用户设备i的活动组Ki和干扰集K'i; 对于用户设备i的活动集合Ki，将所有活动站点ki的所有其他用户设备j的发送信号的叠加彼此抵消，以获得权重的一个约束条件，并且对于M个用户设备M 获得约束条件，确定权重子空间T; 并且根据用户设备i的干扰集合K'i中的用户设备i的另一个用户设备j的干扰信号和用户设备i中的用户设备i的有用信号在活动集合Ki中的加权子空间中确定一个权重 的用户设备i。
