    Abstract: Embodiments of the present invention provide a signal processing method and a base station. By using respective sparse characteristics of a user signal and an interference signal, the user signal and the interference signal are iteratively recovered, that is, the interference signal is first fastened, and the user signal is recovered; and then the user signal is fastened, and the interference signal is recovered. In this way, an iteration cycle is repeated until the recovered user signal and the recovered interference signal meet a preset condition, thereby effectively improving interference cancellation performance, achieving relatively good interference suppression.
